Can't add new iptv device+other weird problems?

[Freaky2003]

Hello,
I installed NextPVR on my VPS using docker which worked just fine.
Then I added a new iptv device and imported channles using XC or however it's called.
The login I used has thousand of channels, which might have been too much for nextpvr...
It imported all channels but when I tried to click "save", nothing happened. I closed the setup window and also reloaded the interface page and after some time I saw two iptv devices. One with I think about 16000 channels and one with a little more than 3000 channels. Anyways, thinks have been weird since then: Under "Channels" in the settings page it didn't show me any channels at first, in the "Channels" Tab on the main interface page there where no channels too and when I tried top schedule a recording, no channels where available as well.
I tried deleting my iptv devices, but that didn't work (Ctrl. --> delete did nothing).
Anyways, I removed nextpvr and installed again, but now I can't add a new iptv. The areas ist just blank.

What can I do?

Thanks!

Screenshot don't help we believe you, it is logs that help. If your want to reset to new stop the server delete config.xml and npvr.db3 and restart.

Don't leave 16000 channels in NextPVR that's crazy, you need to prune some before adding .
