Ufile is a muche cheaper solution...
T2038, see around boxes G,H, I, J, don't remember from memory. It says "enter the smallest value between two boxes", but it puts the difference there. I called them, they agreed it's a bug and fixed it 3 days later. Great. But one month later, after another update, that line is back to being the difference of the other two lines, not the smallest...I can't keep checking manually each time if they broke something else again...
And yes, your findings correspond to mine. Removing those values makes the declaration valid, but it's not the correct way.
