Digital Dashboard Speedometer is Broken (says {{data...)

Firstly, this doesn't have anything to do with the new update, this was happening before the update and was working fine a while back.

Some vehicles (mods) with a digital speedometer on the dashboard (show the number in mph/kmh) are broken and say "{{data" and then it's cut off. Originally this hasn't been happening but some unknown thing must've broken it, and I'm curious as how to fix this. I've already tried clearing cache and verifying integrity, so is there some other fix to this?

 

Those mods are old so clearing cache, verifying game files etc will not do anything. You should fix those mods yourself

 

That's what I'm asking, how would I fix the mods?
