Unable to Verify when posting links & correcting grammar

I keep having this issue and I'm not sure what to do. 

For years I corrected grammar on IMDb and had no issues whatsoever in having changes approved. Then suddenly everything seemed to be flagged and kicked back, right after they added the "Interesting" option where you can vote trivia and goofs up or down. Now I'm inexplicably about 50/50 with corrections. Some things will be approved and the most random things will be declined as "unable to verify", and it's often things that have no legitimate reason to be declined. 

• There are several in my edit history where all I did was add links to information that was already there, and the receipt says it was declined because it was "unable to verify". I'm puzzled and frustrated as to why I keep getting this. I followed the [link=...] formatting correctly so I'm really unsure as to why it was declined.
• Ditto for some grammatical corrections too. Why would grammar have to be verified? 
• As a separate issue, sometimes an edit is approved, then pulled down for some reason. For instance, on one episode I inserted a bit of trivia as to to the basis of the episode (Law & Order is "ripped from the headlines" after all) and it was approved and viewable, then someone pulled it and it says in my history "unable to verify". This was obviously not corrected by a human, as it is easily Googled and verified within seconds. This was probably well over a year ago, and yet despite being re-submitted it's still not there https://www.imdb.com/title/tt0966156/trivia/?ref_=tt_ql_trv 
• There are also several places where someone listed a goof as trivia, so I tried to delete them from trivia and re-submit them into the goof section where they belong, but they were also declined as "unable to verify" so the goof remains in the wrong place. Those 3 hateful little words are frustrating me so much!

Attempted Remedies:

• I have re-written some bits of trivia and some grammatical edits multiple times, and they're still declined, over and over again, for no reason I can discern
• I have followed the instructions to re-submit, but I do not get the "check these updates" option nor do I get any opportunity to insert a reason. Just last night I tried to re-submit something and there was no way to check a box or pull down an option to "explain the edit" as it instructs. The directions for remedying the situation are very poor and leave us with few to no options. It's extremely frustrating.

My biggest problem at the moment is that even inserting links, using IMDb's formatting requirements, are being declined and I have no idea why. One example is here: https://www.imdb.com/title/tt6746132/trivia/?ref_=tt_ql_trv. I put in the links to the specific episodes but my edit history says:
