not getting anything added to Tanzania Collection

ugh, have been trying for weeks to add to the Tanzania collection with no luck whatsoever, even when I have many suitcases to open none of them contain collection pieces. It took some time to get the first 7 countries collections but not nearly as long as
I have been working on Tanzania. I am about ready to delete this game as I am just getting too frustrated. This is supposed to be fun, enjoy a challenge but this is getting past ridiculous.

Stuck in Tanzania

I have played through 4 full levels, nearly five, in Tanzania after returning with 11/20 collection items gotten (Silver Club). I have played multiple games, as is obvious by the level increases, and have played through all 4 of my cards with the 2X power
ups, but I have not gotten anymore collection items. I know it's in the tickets, and there have been times when I've gotten well over 300 tickets in a hand, but still nothing. Am I stuck is or Tanzania harder than the other destinations as I've completed
the Silver Club level collection items in all the others 20/20? I'm getting disgusted since I actually should have this completed. When I reach level 81, which will be very shortly, I will be in Gold Club in France and plan to leave Tanzania and go for completing
France. Am I the only one?

 

tanzania silver club

ive recently unlocked the tanzania silver level but the collection levels have not changed. i believe that each item should be available for a second time, am i wrong?
