Experiencing an issue with HABPanel on my Raspberry Pi touchscreen

I’m experiencing an issue with HABPanel on my Raspberry Pi touchscreen.

I’m running openHABian on a Raspberry Pi. When I access Main UI from my laptop, everything works correctly. If I click HABPanel, my dashboard loads without any problems.

However, on the Raspberry Pi’s touchscreen, when I open Main UI and click HABPanel, the page loads as if it has no configuration, like the first time. The HABPanel configuration has already been set under Settings → UI → HABPanel → Experts Only, and the changes have been saved.

So the issue only occurs on the Raspberry Pi touchscreen. The same HABPanel works correctly when accessed from my laptop browser.

Has anyone experienced the same issue or knows what might be causing it?

Raspberry Pi / openHAB 5.0.1
