Afaict the 1.7.10 version doesn't yet fully support 3rd party mods which add custom entities (in your case at least the animals+ mod).
You'll have to remove any such mods to use the keyframes or the replay editor until the issue is fixed. Afaict, the problem is not in the recording, so, once fixed, even replays recorded with the broken version should be working with the fixed one.
Ticket for reference: https://bugs.replaymod.com/show_bug.cgi?id=117

That sounds good, I think I will keep my animals+, since I think the mods adds a new layer of atmosphere :).
I will wait, until the issue is fixed, and then try to use the mod again.

TY for the fast answer, and I am happy that, you are investigating this issue.
