SecureCRT - "The session name is not valid"

I'm trying to import/add a connection using the SecureCRT Addon/Integration.
I can get this to work when I use 'Direct' under General > Source and entering an IP-address or hostname.

When I use 'Local session' or 'Shared Session' I can't get it to work. If I select 'Local session' and then select the correct .ini file in c:\Users\user\AppData\Roaming\VanDyke\Config\Sessions\server.example.ini

I get an 'The session name is not valid' error. Can anyone tell me what I'm doing wrong?

Using RDM version 2025.2.20 and SecureCRT 9.3.2
