[Bug]: Unable to remove manually configured network

Describe the bug

Usually, the 3-dot overflow menu next to a network in a network picker would allow removing that network. It does that for all of the custom networks I added, except for a ROAR testnet entry I added recently, for whatever reason. I'm now stuck with it and it's unclear why it cannot be removed.

The option to delete the network doesn't appear for no clear reason:

Steps to reproduce

(I'm unsure as to the root cause of this and cannot reliably reproduce it)
