I think this is related to another issue I tried to describe here:

https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=872036#Post872036

"The user can maintain several views simultaneously, yes, but these views behave as if they were completely independent, which is not only counter-intuitive but (even worse) is a guarantee of unexpected behavious and bugs from the program. For instance, if we keep the "Chords" and "Tracks" views active simultaneously and select measures 1 to 4 in the first and 5 to 6 in the second, and then press the "Del" key, how will the program know exactly what we want to delete?

Note:Try it and you will see a very strange bug in the program."
