Form appears differently from UAT and PROD.

A Regenerate form in General Ledger in our UAT instance does not look the same as the  form in Production. The same form, however, for the two development instances  that were recently cloned from this UAT instance is the same as in Production. The form behaves same in dev and prod and in uat it looks different.

Following steps were performed but the issue remains :

1.  We've tried replacing the GLXRJGEN.fmb in UAT from production and regenerated the GLXRJGEN.fmx

2.  We've tried to  generate the form files through ADADMIN utility

3.  Reran perl adcfgclone appsTier

4.  There are no customizations on the form.
