imported music xml with slashes problem

I received a lot of scores with a lot of slash regions exported from Finale (xml vers. 3.1).
Almost everything looks good - except chords like *7(b9) imports as *7(add9), and a lot of places the slash region is broken (so there’s one bar of notes + a repeat sign, and then the next region starts).
I don’t know if it’s a Finale or Dorico problem. Is there a way to correct this or do I have to do it manually ?
Another thing - is there a way hide all “bar count in slash regions” or is this also a manual thing ?
TIA,

You’ll have to fix these issues manually after import. You can specify whether or not the bar count should appear for slash regions on the Notes page of Engraving Options.
