I forgot to add:
Tested with latest KDE and Firefox 128.0.3 (64-bit) and uploads only first file.
Seems that previous Firefox version was working OK.
I just tested it with Chrome 127.0.6533.72 and it is working fine, upload all files!

[susnux]

Tested with [...] Firefox 128.0.3 and uploads only first file.
Seems that previous Firefox version was working
tested it with Chrome 127.0.6533.72 and it is working fine

So this is a browser issue?

[sstefanov]

Seems yes. I just tested with same Firefox on Windows 10 and it works!
I'll close this issue, probably it is due browser problems.
