It takes sometimes days, usually weeks at best, and sometimes decades (if flanker, lockon inheritage are taken into account) to get bugs squashed in DCS.
Which are the ones that irritate you most, and if you remember, how old are they to this date ?
Here are two of mines, one for ED and one for leatherneck:
EWR callsigns: there are almost twenty in the ME choice, only the 5 first get you a working EWR, and the vocal callsign used is different from the written one ! Call darknight, magic will answer.
Mig-21 lights: taxi light illuminates front and left, landing light adds right side but with sale intensity. When the plane is without any power, all three landing gears have a dim yellow lighting.
I think those have always been there. I have others that I need to check again.
So, what are yours ?
