Schedules that are disabled show the red dot with the exclamation mark - same as for down resources. This is much too "aggressive", it is more fat than the green ok sign and just looks like something bad happened. This should be replaced either by a fine red X or a dash or 'no' - but with an optical weight that is adequate for the small green ok sign.
Fixed in BooleanCellFormatter, which is also used by some other Tables - [master 779b977].
Checked in the latest master build, the schedules that are disabled show a dash which I believe is fixed now. However, the down resources, still show exclamation mark in Red. Moving it back to ON_DEV for confirmation.
Can you clarify where you're seeing a red exclamation mark and/or attach a screenshot?
Created attachment 485732 [details] screenshot This looks good to me - was perhaps a refresh issue before.

I see what Heiko see. I also, checked the downed resources for which I moved it back, attaching the screen shot.
Red exclamation marks are perfect for downed resources, but not for schedules that are just not enabled.
Ah, may be I misunderstood the initial description. Marking this bug as verified.
Bookkeeping - closing bug - fixed in recent release.
