How to correct airport data? Seattle Avionics? Dynon?

[RandomSquawk]

I have the latest data from Dynon and Seattle Avionics loaded into my HDX. I encountered an airport traffic pattern (TPA and direction) where the HDX is giving incorrect information. It seems the suggested pattern, direction, altitude are all applicable to helicopters only. I've never seen this before. Multiple popular aviation apps all agree with the sectional and local pilots, so the problem must be unique to the way the HDX data is sourced. Where & how would I submit such a correction?

I discovered that FlyQ-EFB has similar error, so I will poke Seattle Avionics and see what they say.

Errors in the data need to be reported to the FAA.
