Hi, 

I'm facing an issue in referencing the Int class rules in work class rules.

Work class : Major-Minor-Work-pqr-.. (This is in Alpha ruleset)

Int class: Major-Minor-Int-abc-.. (This is in Gamma ruleset)

Currently I created an activity rule "TestAct" in work class and Alpha ruleset branch, trying to refer the Int class in pages & classes tab, but getting the below error - 

"Class Major-Minor-Int-abc-.. does not exist or is not a valid entry for this ruleset and its prerequisites"

Both Alpha and Gamma rulesets are present in the app stack in the same order, also both the rulesets are in application validation mode.
