Merging entries

Hi,I have to apologise as I have just realised I've made a mistake with two new entries I've created:#260405-161955-401000 and #260405-173505-188000

These credits, which are attributed to episodes 5.1 and 5.6, should be for episodes 4.1 and 4.6 for which entries exist but do not have the credits.

To fix this, can I request the credits be transferred from 5.1 and 5.6 to 4.1 and 4.6, or should I request the removal of 5.1 & 5.6 and re-enter the changes to 4.1 & 4.6.

Really sorry for this mistake. I hope it's the possible to merge them but serve me right if I have to redo it.
