Short description of error

In video editing the subtitles working really different now, the way I use to do subtitles is place a text strip over where I need it, colour it to the person talking, animate any zoom/fade in & out with the start and end of a text strip, then if applicable, animate the text to be above the person speaking. At this point, it's just video of a game with the word "text" over someones head, it fades in and stays above their head, but it just says "text", so I cut it up for each word said in the sentence, so one stip turns into many, then type the words in each stip.

It use to just work, the cut strips would still do what I told the original srip to do, eg. (1 strip = [fade in + zoom in] -> [change strip text to "y\./y" the "y" to see where lower letters will be, "\" to see where high will be, and ". " to see the center so I can easily track where to animate it to on the screen] -> [go to x-418 y290] -> [go to x-400 y170] ("go to" part is every 4-6 frames of the strip) -> [fade+zoom out] -> [cut the strip up for each individual word] -> [type the words])

It would then be how I want it, then I could cut it and type the text and it would still animate for all the cut strips, in 3.1.0, now when I cut strips, the cut strips are just where they are the the animating I just did only effects the last cut. So now I have to go back over every single cut strip and animate them ALL individually, with there being thousands of words in a video, this is very frustrating

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

start blender
open video editing file
