Missing/Deprecated highlight group(?)

A few days ago I lost my Neovim configs so naturally, my which-key config was lost as well... Anyways, I started to reconfigure it and noticed that a highlight group wasn't applying. I don't know what it was (configured it a while back) but, my best guess is the WhichKeySeperator group(?) Used to have a cool aesthetic effect on my separators:

Before

Notice the slight blue line at the end?

After

I can't seem to replicate it no matter how I try.

Other relevant info

Following are the which-key configs and highlight configs

which-key config
