What is the proper way to remove/add a Private Channel with same name?

I’m Running Rocket.Chat Server 0.73.2. I have a need to replace some of our existing read only channels with read only broadcast channels. Before doing this to the existing live channel, I created a few test channels to reproduce what I had and the changes I wanted to achieve.

It seemed to have some issues when trying to delete, it kept giving a floating pop up in the top right saying invalid channel. Also had issues on various clients (web/pc/mac) where it would just hang with the three dot throbber like it was thinking about it, but never loaded. This was a member trying to leave a channel.

Is there any guidance on the proper way to remove/add a Private Channel back in with same name as prior?
Thanks.
