One of your agencies is trying to give you authority to access their environment without giving you full-blown Admin access.
You can get into their Endevor, but on the Primary Options Panel, there is no number 4 -- there is a blank in front of "ENVIRONMENT - Define or modify environment information" instead of a number, and you cannot select it.
You suggested you have READ access to class $ENDEVOR profiles C2.ESI.*.PMENU.ENVRMENT and C2.ESI.*.*.*.ENVRNMGR.
This did not have the desired result of making option 4 available. What profile is checked to make option 4 available?
Resolution
Endevor is secured by profiles in the $ENDEVOR class
Do a SETROPTS REFRESH RACLIST($ENDEVOR) to resolve the problem.
