Search help going into backgroud of Adobe form , making whole form disbaled.

Dear Experts  ,

I am  facing a unique issue in Adobe form Search help in HCM form and processes .

When i click on the search help of any field it open the search window pop up but once i try to give anything in search criteria in the Search window it goes into background of the Adobe form making everything else disabled and also the search window is  not accessible as it goes in the background .

What could be the possible issue for this kind of behavior of the Adobe form .

PFA the screenshots for clarity .

Any input is highly appreciated .

Thanks

Regards~
