Generic Import Transaction Matcher, no amounts

[Ken Runge]

QFX imports from one of my bank accounts are showing $0 in the amounts 
column of the Generic Import Transaction Matcher, the other columns in 
the Matcher look OK . This is only happening with imports from one 
specific CC bank account and does not happen with imports from any other 
CC or C/A bank account. I have compared the problem file with one that 
works and can find no relevant differences. The lines relating to the 
amount are identical (except for a value of the amount of course). I 
have also loaded the problem file into Quicken (still have it around) 
and it loaded properly so I am inclined to believe the problem is not 
with the file itself. Question is, what could I have done to GC, in the 
setting or elsewhere, to cause this?

I am at a loss as to where to look next. Any suggestions would be most 
appreciated.
