Issue in Parameter simulation when script recorded with multiple action blocks

Hi,

I am using Loadrunner 12.53 version for http protocol. I am facing issue with parameter simulation when my recorded script consists of multiple Action blocks between vuser_init and vuser_end.

My parameter consists of 3 usernames: lruser, lruser1, lruser 2

Configuration used:

Select next row: unique

Update value on : once

No. of vusers: 3

No. of iterations: 3

Expected result:

             iteration1  iteration2   iteration3

user1    lruser         lruser         lruser

user2    lruser1       lruser1       lruser1 

user3    lruser2       lruser2      lruser2

Actual result:        

lruser   lruser    lruser

-             -           -

-             -           -

Note: Parameter simulation is working fine when recorded script consists of single Action

Screenshots attached for reference.
