I've encounter this problem too with the last update.  Was working fine before  update and I use Form 2555 all the time. Over 65% of my business is overseas folks.  This is stopping me in my tracks for I can't transmit  any of my returns with the errors.

The error is stating that I do not have dates in the PPT field when I do nor any values in the field to exclude when I do.  I attempted to delete and reinput data, but the error is still there.  I tried a recalc, no luck  I checked the allocation worksheet and that is all in order.  So can find no reason for error.
