After a little more testing it appears that it only fails to properly find computers that have been renamed. If I filter for a current, active computer it comes up (with a little bit of Error: Invalid Value struggling)
File 1 - Default options, type in name of computer, Invalid value
File 2 - List of operators doesn't include "like"
File 3 - Why are there 2 "Computer" options?
File 4 - Select Description, "Like" Operator appears, switch back to the 2nd "computer" option, (selecting the 1st "computer" option reverts back to "equals" operator)
Bang head on desk.
Proceed with filter.
