XML file crams empty measures together....how to separate

I have found XML imports to be very good, but have run into an issue where measures notated as multimeasure rests in the orignal score come out as empty measures crammed together; I can delete them, but when I try to put measures back into the space, I still get as you can see in the middle of the attached file…any ideas?

Select All.
Filter (select)>Notes and Chords. (to show the note properties)
Reset the Ends Voice property. (also Starts voice if, in future cases, that switch is activated)
