I've been playing my recently purchased WOFF UE using "easy" claims.
However I found the following bug with "easy" claims in WOFF UE:
If you shot down an aircraft of a certain type, lets say a Fokker DII you can make the number of claims you desire of that same type for aircraft (again for example the Fokker DII) and they will be accepted!
For example and after noticing this, in one mission where I shot down 1 (one) Fokker DII I filled the following claim list:
1 - Fokker DII
1 - Fokker DII
1 - Fokker DII
1 - Alb DII
1 - Alb DII
1 - Roland CII
All Fokker DII claims were accepted (despite having shot down only one Fokker DII) while the other 3 claims (Alb DII and Roland) were rejected as expected since I didn't shot down any of these aircraft and neither as far as I know any of these aircraft were present in the area.
Then, I did another mission in order to confirm my findings where my flight of two Strutters found a flight of two enemy Fokker DII's, with me shooting down one of the Fokkers while my wingman shot down the other and after the mission ended I claimed the following list with 6 (six) Fokker DII's:
1 - Fokker DII
1 - Fokker DII
1 - Fokker DII
1 - Fokker DII
1 - Fokker DII
1 - Fokker DII
And again to my surprise, all these 6 claims where accepted (when in fact I only shot down one).
Again, this happens while having the claim systems on "easy".
