1. PARAM, LGDISP,1 is used to activate large displacement analysis for all subcases containing the NLPARM or NLCTRL Subcase Information Entry in the model. Subcase-specific Large Displacement Analysis can be activated via NLPARM(LGDISP)=SID, wherein, SID references a NLPARM Bulk Data Entry.

In subcase definition when I click on NLPARM LGDISP, I get option to select loadcollector.

In loadcollector I am unable to see option for LGDISP shown in images above.

I seem to recall this was an issue that has been resolved. Can you please try updating to a newer version and see if you see the same behavior?

Updating to latest version might be difficult. Is there no other option like editing .fem file to put on the parameter.

I am not able to reproduce the issue

I would either disable filtering or trying deleting temporary settings files

Filtering is removed but I am still getting the same issue. I will ask company admin to remove setting file as I don't have permission to do it & come back to you if the problem is still there.
