Text+ Keyframe no longer works correctly

Hello.
I want to keyframe the Text in a Text+ on the edit page.
Add Text+
Enter Text & set a keyframe
move 2 seconds and set another keyframe
move 1 frame, remove text, and set a keyframe
move 5 seconds, add a keyframe
move 1 frame, add text, and set a keyframe
move 3 seconds, add a keyframe
Regardless of switching the cache off, deleting the cache, etc it doesn't keyframe the Text.
