Report Fields disappearing after mapping parameter

I have made some further modifications and I hope the this time we have fixed the problem. 

The bug is back 4.61 release

We will double check it

I have spent half a day today trying to reproduce the problem and I was not able to do so.

It works absolutely fine here

Maybe try a query with two parameters or slightly more complex parameters

I can confirm bug in below . I have passed relevant parameters by using variables.

ORDER BY

I 've tried and it is still working absolutely fine.

After approximately 1 sec the fields are refreshed.
