Cannot connect to second wifi profile

Hello, so I was able to successfully connect my rpi to my home network using Berrylan. I then took the rpi to a friends house and tried to connect to their wifi, however I was not able to. The BT-WLAN pops up, however once I select it, it goes to the next step, but does not show any networks. Then it goes back to bluetooth and BT-WLAN is not shown anymore. Do I have to remove my previous network every time to connect to a new one? Thanks!

It’s most likely a channel 13 issue.
