I'm not sure if there's a way to fix this but...
I'm doing the event quest at the moment to receive that specific region for this week and the gGda coins that i got from monster chests at Dragon Valley are being counted for the quest but the ones that I bought in market aren't. Is there something I'm not doing right? When I purchased Gada coins for week 1 and week 2 it automatically combined into the stack of coins I already got from hunting. What's going on?
