|Title||WATO GUI rule matching: Fixed broken evaluation of negated WATO rules|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
The rule matching algorithm failed, if there was a negated service or item specified. Instead of a negative match, a positive match was returned. This has been fixed. Note: This was a GUI only bug, it didn't have any effect on the actual monitoring.
