KDE: many config files lo_kde5filepickerrc.lock

Hi.

System Specs:

OS: Debian 10 with KDE
LO: 6.1.5.2

Problem:

When open or import any kind of files with Impress, LibreOffice creates on ~/.config folder many same files:

lo_kde5filepickerrc.lock  

lo_kde5filepickerrc.lock.rmlock  

lo_kde5filepickerrc.lock.rmlock.rmlock  

lo_kde5filepickerrc.lock.rmlock.rmlock.rmlock    

lo_kde5filepickerrc.lock.rmlock.rmlock.rmlock.rmlock  

Is it possible to disable create these files?

I’d say, it looks like some bug, which should be reported appropriately.
