error 95365

[GWGWGW]

I get the error messages that 52/53 do not match 21.

However I have original T3's with values in box 21 but 0 in box 52 and 53 (. and if I add the 21 value into like 53 it increases what I owe as if it counts it on top of 21. These original have values in 49/50/51... 

But if this error expects that every T3 that has a box 21 needs also values in 52/53 I have a problem.
