I can't edit my text properly.

I first want to say that maybe something has changed inside the program, but i have been editing text this way previously, especialy when having a need for fast captions, and all of a sudden its broken.

I have labeled things 1-5 so that i can explain easier what the issues is.

I have a presset that I made which is a simple 3 keyframes scale popup animation (1/5), which when applied to text doesn't change anything (2) but instead just adds another "Source Text" i guess on top of the existing one (3).

Arrows 2 and 3 show the exact problem that I have, as you can see with arrows 4 and 5 the only thing changed with keyframes is "Scale" (Source Text) was not touched, yet when I apply the presset it messes everything up.
