For NGR, it looks like the story-mode completion medal has been fixed. I checked my data (after having beaten every story a few hours ago) and it is now at 100%. Once you enter a battle you should get the medal, and the 100% medal if you've already done everything else.
Other than that, I haven't noticed any problems with the game's medals.

I think instead of using it what you have to do is make it so you have total 5000 newgrounds gold, and then instead of spending it right away you need to enter a fight and it should give you the medal as soon as the fight starts.
Entering a fight seems to work. I got it by going to the data screen when I had about 5300 gold.
