UI version is 11.2.1 build 412, JRE version is 1.8.0_144. The two AE's are version 11.2.1 build 412. The search option is Y is both AEs. One always works fine, in the other is working sporadically; grayed out somtimes, other times it works fine.
Unfortunately it is the production AE that is working sporadically and don't really want to test with the L option.
