Occasional bar lines added through entire score instead of just through systems

[PTPi]

MuseScoreNightly-202407160427 and earlier, full score bar lines are being added randomly over system bar lines to scores that were created with 3.6.2. The visual result is a thicker system bar line and a single, thinner bar line incorrectly joining the systems. The issue does not appear on every page. Where it does, it only occurs once per page. I can provide both the score and a screenshot if needed.

The attached zip file contains - the score for an unfinished string nonet created with 3.6.2 - a screenshot of page 4 showing one of the wonky barlines I coined the term full-score bars to describe the error. As you'll see in the screenshot, such barlines run the entire depth of the score from the top staff/system right to the bottom staff/system with no break between systems. The score I've attached has other layout problems, but I assume those are to be expected when migrating from 3.6.2 to 3.7. Sidenote: thanks so much, JoJo, for pursuing this fork of 3.6. 4.0 is completely unusable for my purposes. 3.6.2 was getting close to perfect.

I replied to the auto-generated email sent to my local address. Records show I did attach the zip file. Perhaps github rejected it? At any rate, I'm drag and dropping the file into the comment area of this thread. Hope it shows up.

Yes, replies via email do loose their attachments
Here the screenshot:

And yes, I can confirm the issue with 3.7, and it being a regression vs. 3.6.2. Not an issue with Mu4.

Selecting the measures ending with that messy barlines and pressing return twice (i.e. adding and removing a system break) seems to fix it.
Note: these are places where 3.6.2 would automatically break the system/page!

Something odd is happening in measure 53; all clefs and key signatures are repeated.In 3.6.2 and 3.7. And the key signature can't get deleted ?!? It doesn't show a measure number, even when it is the first measure in a system, it is always hidden, but why?

[PTPi]

I'm not seeing the repeated key/time signatures at bar 53, rather at bar 114. I do, however, notice the missing bar number at 53. I can fix the repeated key/time signatures by selecting them and unchecking "Show courtesy" in the Inspector.

[Jojo-Schmitz]

Clef and key signature, but yes there too. Isn't there a section break missing?

At 53 you'd seem it after the "twice return" trick to fix the barlines.

Is this better?
