Time Compressing Tool Problem

Lets say you have an audio file with 3 dialogues. You split them in 3 parts( 1 dialogue each) and want to time compress the first dialogue with the time compressing tool ( mpex only…realtime don´t even show up in DOP when used). Then you compress the same audio again. If you undo-it twice everything is fine, but if you select the 2 time stretch that are in DOP and delete them, the whole file shows up covering the other 2 splitted files.

Can anybody repro this?
