oUF - Layout discussion

[Generizer]

Hi There. I'm very new to oUF and lua coding in general and I've had an issue arise since 3.1 hit and I really have no idea how to fix it.

I've been using the oUF_Maneut layout and when 3.1 dropped the custom coloring on my target frame disappeared.

Here is a before shot


Here is an after shot


Any ideas on what to change/update to get it working again ?

Thank you in advance.
