Simple Form Row Function not working [1] - Planning 11.1.2.4.010

We are experiencing an issue which seems to have been introduced by our latest patch(31365862) . The issue is basically that forms have stopped working in two different applications, in two different circumstances. There is something in common between the two sets of forms, both have row formulas making references to row which returns multiple rows (i.e. [1]). The purpose of these formula rows is to present or do a validation with the summation of the source rows, so similar to SUM[1].

You would say why wouldn't you user the parent of aggregated member of such members, and the answer is that we used to have an issue pulling the data but since the related dimension (Entity) was set to dynamic at the upper level members even though it is sparse.
