Contributions repeatedly declined; not sure why

Hello. I am a new IMDb user who has been working to try and update and correct information pertaining to the site entry for the TV series "Sonic the Hedgehog (1993-1994)". Almost all of my submitted contributions have been repeatedly declined with little explanation which has been quite frustrating. I am determined to fix the errors present for this entry and add info as well and would like to get some concrete answers as to why my contributions keep getting declined. It looks to me like this forum is the best place to make such an inquiry as it does not appear that IMDb welcomes users to submit questions to staff directly. Here are just some examples of contributions that were declined: #250312-083532-434000 - This external link to an image of a poster was rejected despite other links to alternate posters being accepted #250312-083229-691000 - These genre additions were all declined despite the fact that anyone who has viewed this TV series would attest to their truthfulness #250312-082644-100000 - These two alternative informal titles were rejected despite them being by far the most common names for this TV series internationally, more so than the official title of the show itself #250312-081731-765000 - For some reason even simply adding the tag to individual episodes that they were produced and exist in a 4:3 format was declined #250312-080935-134000 - Most frustrating of all is that this reworking of the plot outline was rejected twice. I sincerely believe that there is no issue with this write up and that it helps to paint a more accurate description of the show's plot and story Also, there are some images present on the page for this entry that do not originate or belong to this material and were obviously uploaded by someone who did not have an awareness of this. I made a request that these images be removed on the grounds that they do not pertain to the specific entry on the database. When I clicked submit I received a confirmation number yet for some reason any of the contributions related to uploading or editing images never appear in my contributions history so I cannot track them and they seem to have had no effect. Lastly, my understanding is that regular users cannot upload video clips directly to an entry's page, yet I also do not see an option to report issues with clips that are already present on a page and for this specific entry there are once again video clips present that have no relation to the material and originate from other TV shows. I am not sure how to fix/report this issue. I am quite versed in the knowledge pertaining to this exact TV show and can pledge that all of my edits or additions are absolutely based in truth. I am not sure what else I can do to prove that other than providing countless timestamps to exact moments in episodes to prove my claims, which I doubt any person working on IMDb's end will actually review or understand. I am determined to fix these issues with the database entry.
