Problems with capo in guitar diagrams

Hi, Gang!!!

I use MuseScore 3.0.5 (not the Portable AppImage) in Ubuntu Studio 18.04.2 LTS (64 bit Linux).

With the file I added, I have a problem I don't know it is a bug...

I put some guitar diagram chords in that score and, I can sure you, I put the correspondent capo bars where it should be.

The problem is... When I reopen the same file... The capo bars are not where they should be!!!

There is no capo bar indication in the Eb, Ab, and Bb chords!!!

I repeated the edition of those chords, putting the capo bars again. I saved the file. I reopened the file, and...

The capo bars aren't there!!!

Who stole the capo bars? ???

The curious thing is... The capo bars are In the exported PDF file!!!

So...

Please... Help!!!

Blessings and Greetings from Chile, South America!!!
