Concluded credit transaction incorrectly shows channel is closed

Thanks! You are right. The messaging is confusing. I will fix it.

This problem persists. Under "Channel Status" the credit transaction page says "Active," but between the two node boxes it says "Channel closed" despite that the channel is in fact still open.

Can you kindly check if the bug has been fixed on your end?

Now the concluded credit transactions that say "Channel Status: Active" do say "Channel detected" instead of "Channel closed." However, that is not always correct. Take a look at credit transaction #3185 for example: the channel funding output was spent on 12 December, yet LN+ still shows the channel as open. 

Thanks for checking on both issues. Regarding the closed channels I'm unsure what to do, because I both check them on LN gossip and directly on mempool, but it's not always picked up still. Mempool also shows the channel as open.

Indeed. I would think eventually they should expire out of gossip since they're no longer being advertised, right? Might take a few weeks, though.

Let's hope so. I will keep checking it to see if it happens.
