Resolved "Source Control" tag not showing for one of my projects using PlasticSCM

I have a few projects on the go all using PlasticSCM. All but one show the "Source Control" tag. You can see it in the image.
It's not the end of the world, but it made me wonder where that tag is set. I tried looking through ProjectSettings etc and couldn't find anything.
When I go to "Open Remote Project" it also shows an option to download when it shouldn't be as it's already downloaded.
This is consistent across all my devices too, desktop PC, Macbook, and Windows Laptop.

Does anyone know what could cause this? Or what file do I need to change to get it to show properly?

 

I actually worked out the issue by mistake.
I was parsing the YAML in another program I'm making, and it kept failing to parse.
Turned out it was due to a malformed YAML. In this case the "scriptingDefineSymbols" property.

After removing that rogue value it's working fine now.
No idea how that got there lol.
I'm so curious about how the engine was handling that...

Its working fine now, I'm happy
