It is not possible to change the icon for .gpx files

Have a good time of day to everyone!
I can’t change the icon .gpx files… Both in the system settings and directly in the file settings, the icon I installed is displayed, but in Dolphin, for some reason, another icon is displayed.
What can be done to solve this “problem”?

I can’t understand it… Is this a Plasma or Dolphin bug?
In the VM, I did a clean install of Endeavour - everything is as described above.
But if you install Nautilus or Krusader, it is displayed correctly in them.
If Dolphin disables the creation of previews for files .txt, then and files .gpx displays the icons that I assign to the file.
Wonders…
