Fields in Grid doesn't have the internal value to open Linked Applications

I’m adding two fields on a grid, and i have a linked application (same application for both fields) to each field and i use parameters (Fields- Get) to open the applications.

When i run the application the grid asign the parameter values only to the second (last) field, so i can only open the Linked application to the second field witch it has correctly asigned the parametes.

I “solved” this showing all the fields when i run the grid , this way the grid asign correctly the parametets to the Links, but this is not the solution that i need, because the grid looks overloaded of data from the parameters

Thanks in advance for your support
Best,
Arturo
