Hello,
I have a frustrating problem or a lack of know-how, and I have never seen something like this only in After Effetcs 2017.

Can somebody please tell me am I doing something wrong or maybe if this is an error, is there a way to avoid it?
PS
If I delete all existing points and try to create new, I still get this problem...

Nice! Thank You so much! I wouldn't ever guess the name for this to find a solution...
