Coin dozer app problem?

I'm having trouble with this app and it most likely wont have an update but its called coin dozer. Its my favorite app and i like to see how many points i can get. i know it may not seem like a big deal but its had me puzzled for awhile! I'm on level 106 and have almost every tier for the prizes unlocked. there are 5 or 4 different colors for around 5 or 6 prizes. I have more than 6 for each prize but i dont have ANY yellow bears. it hasnt given me any at all and im sure of it. has anyone else experienced these problems? I was just wonderin because there probably isnt any way to fix it but let me know if this is happening to you. Thank you!!!
