Howdy! :-)
This could be considered a missing feature rather than a bug, but i didn't want to clutter your comments any more than i already have with my waffle!

[REPORT]
1. Whip's Group Renamer v7 - 08/04/2019
2. "Add space after prefixes" only affects grid prefix not custom prefix
3. change the setting to false in the config and rename with a custom prefix and there will still be a space

so i have changed it in my local copy of the code (have actually hard coded the space with an underscore rather than adding the config feature), but wanted to mention it in case you ever do another update - not that i expect you to since the script is top notch and possibly i'm the only person who has an obsession with underscores :-) and as you can see i can make simple changes myself - just thought would mention it

Anyway, thanks for all the awesome code! :-)

1) Version 7
2) When using the scrip the "x" for "prefix" is added when adding prefixes in modded runs
3) Modded world https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2291651793

Something is very wrong with your prefix and I can't figure out what is going on. I deleted your group, then recreated it and it worked fine. When I manually typed the "prefix Miner" group it created a duplicate group. If they are the same name, the game will merge them. I'm not sure what is going on, but try deleting that group, then manually recreate the group, retyping the group name.

EDIT: Ahh... It looks like there is a newline character in the group name which is odd...
