Exalate does not support queries containing OR (and, conversely, ^NQ) operator, like in the following query:
Exalate keeps track of the last time when it executed a query and with every next sync, it only takes into account changes that were made since the previous sync.
To do that Exalate adds
sys_updated_on>= a clause to the original trigger query.
In case the query contains
sys_updated_on>= only affects the left-hand side part of the query.
There are 2 possible workarounds for this issue.
You may split the query into 2 separate triggers:
As a solution, you can use a conditional checkbox field and reference it from the trigger query
