The 1040 in question has multiple partnerships to report.

Some of the related 1065 K-1s are prepared by us on Lacerte. We are finding that the export of one 1065 K-1 to the 1040 overrides & blocks an earlier 1065's exported k-1's information for the same 1040.

When we try to override the 1040 data by manually entering the 2d k-1 info, we find the initial imported info is deleted. There's a gremlin in all this somewhere.

We have tried alternating the sequence of exports, & the problem continues.
