MusicXML import — What's the easiest way to delete overfilled portions of measures?

I have decades of legacy scores in Encore 5 format. Foruntately I can export to MusicXML (I believe in MusicXML version 1.3)

I get good results opening Encore's exported XML in MuseScore ... with an interesting exception:

When Encore exports a score containing a tablature staff, on importing the XML MuseScore correctly populates each measure on import but also MuseScore appends an amount of rest that overfills every measure.

Looking at the XML I don't see what prompts MuseScore to overfill measures.

That aside ... I'm wondering, What's the simplest way to delete the tail end of overfilled measures? In other words, how can I truncate anything that exceeds a full measure, deleting from right to left (from the "fully filled" point to the end of the bar?)

I constructed a simple test score in Encore that looks like this:

Here's the exported MusicXML

      Encore XML Export test WITH TAB for MuseScore.xml

I see varying results when importing this MusicXML test into various apps:

• Overture imports it most accurately, without overfilled measures, with stem directions and beaming preserved (and without a populated tablature staff, because, well, Encore does not encode the tablature, except for the staff itself.)
• GuitarPro7 imports it without overfilling measures. It doesn't bother to include an unpopulated tablature staff. It beams the last half of Measure 2, ignoring the beam and stem direction.
• MuseScore imports it but overfills measures with trailing rests and therefore shows a + sign above each treble clef and tablature measure. It beams the last half of Measure 2, rather than showing the unbeamed notes and their stem direction.
• Dorico imports essentially like MuseScore, but oddly with a second treble staff rather than a tablature staff, and like Overture it gets the beaming and stem direction right,

Interesting ...

Suggestions?

For the record I can delete the tablature staff before export MuseScore does not overfill measures, but I'm sure there are a lot of Encore users looking for a viable tool, now that Encore now amounts to flotsam, jetsam and failed promises. And their path into MuseScore would proceed most smoothly if they don't need to figure out workarounds. On the other hand, if the XML is I can delete the tablature staff before export MuseScore does not overfill measures fatally flawed, that's another matter.

Thanks!
