Is my HA broken?

I have problem with my HA.
I am running HA OS on a virtual machine.
Technically there is no problem, but I’d like to mount additional network storage.
So I went to Storage in settings, this is what it says:

The real issue is this:

Did I misconfigure something? Am I doing something wrong?

Have you installed a development build? It’s saying you’re on “11.0.dev20230501”. Version 10.2 came out on the 25th May, which is 2 weeks later than the version you have.

I’ve tried dev version long time ago, then switched back to regular version.

I’d say it doesn’t look like the dev version of OS has been switched back. Since 10.5 is out now, you could try updating to that.

I tried, it worked, now I can add the storage, thanks!
Seems like the downgrade did not worked OK previously.
