Dynamic calc members crossing dim with smart list member does not calculate

Hello, I have the following calculation

Sparse_DimA = @MEMBER(@CONCATENATE("HSP_ID_",@HSPNUMTOSTRING("SmartList Member")))→Sparse_DimB

Where [Sparse_B] is a dynamic calc parent. In this case, the operation is not working. When I change the [Sparse_B] with a level0 store member it does works, and if I try replacing the @MEMBER(@CONCATxxx logic to get the smartlist member value with a fixed member it works as well.

So, it seems the @MEMBER(@CONCAT…. operation is the issue, I tried with

SET HYBRIDBSOINCALCSCRIPT FULL;

SET FRMLBOTTOMUP ON;
SET FRMLRTDYNAMIC ON;
