Apply button circle spiining, never stops

[taztcs]

Hi all,

New install of opnsense (I had pfsense before) and I like it so far.  It has been updated. I have a strange issue.  I am using the DNS blacklist feature in Unbound.  I selected several lists of the ones offered and then I hit the Apply button.  I see the spinning circle, but it never stops.  After about an hour, it was still spinning.  I navigated away from the page and when I went back I could see the selections that I made. I thought all was good.  Later that night, the firewall stopped passing traffic and I had to reboot it though the console.  I found a list that I had chosen was blocking some sites, so I removed it and hit apply.  The same exact thing happened even though I let it run all night. I had to reboot it again through the console.  I have not touched it again as I am afraid.  Has anyone else seen this behavior?  I checked the logs and did not find anything out of the ordinary.  Thanks in advance.
