We are trying to get the selected index value of the table by using the below expression in the activity and we are assigning it to the Param.  "@IndexInPageList("true","pySelectedWritable",pgRepPgSubSectionGeneratePDFBB.pxResults)"

after some runs, the index value is not set properly it is picking up the previously selected value.  

We have tried the set the index param to null at every first and last step in the activity but still, after some runs, it is picking up the previously selected value
