A customer set up a Kanban board with a query on a custom drop down field (ex. named 'CustomText/Field') as follows;
( c_CustomText/Field contains "test" )
However the query is not filtering, no errors are presented.
The problem is the special character '/' in the field name. Users are advised not to include special characters in field names. In order for the query to run, remove the '/' from the name in the query as follows;
( c_CustomTextField contains "test" )
The query should work without having to create a new custom field.
