I have a possible bug/issue with DayPilot 8.1 where the text in the last cell of the header barely appears. I have been tweaking and adjusting the config in angular directive + $scope.config to get it resolved and nothing. Have you seen this before? See picture attachment. Thanks
Can you please post your configuration? I'm not able to reproduce the problem in the online demos.
It looks like a possible CSS issue - do you use the default CSS theme or a custom theme?
