2127757 - Forced merge failing on RLV enabled table - SAP IQ

Forced merge on RLV enabled table is failing due to duplicate key conflict while rows from RLV part of table get merged into base table part ?

Errors can be like this.

------

Could not execute statement.
Tried to insert a duplicate value into a unique index TCA.TCAReportData.ASIQ_IDX_T766_I328_HG on row 67640301.
