Could anyone confirm if Midi Device Manager's GUI is working OK in OSX?

Hi, the editor of the midi device manager is having a lot of GUI problems, most of them in the objects bar:
The name of the selected menu it’s not shown
Half of the backgrounds are not shown
The parameter in the value boxes is not displayed in any of them
The value of the use raster box is not shown
It’s not possible to see the objetcs bar complete.


What macOS version do you use, please? It looks OK here on macOS 10.15.
