I think for Episode Race is broken. Didn't get a rewards for 15 gold bars!

I completed level 11756 but something went wrong with the next level when you beat a level. I think for Episode Race is broken again! Do you see this level 11756 with first try gold medals but I can't open level 11757.

Update: the glitch is been solve but my balance of gold bars is still 324 gold bars. Because the Episode Race is gone because of glitch with next level! (See 1st screenshot)
