Perspective Went Missing After Migrating Ignition From 8.1.26 to 8.1.52 then from 8.1.52 to 8.3.4 version (Latest)

I found an issue when trying to upgrade my client ignition project from 8.1.26 to 8.1.52 then from 8.1.52 to 8.3.34.

I could see perspective section when the project was deployed on Ignition 8.1.26 with designer version 8.1.26.

I upgraded everything to 8.1.52 including the Designer Launcher. I still could see the perspective section.

I upgraded everything to Ignition 8.3.4 including the Designer Launcher. Then the Perspective section went missing.

I think there is a migration issues from 8.1.52 to 8.3.4.

What you guys think ? Let me know.

Regards
