Downtime is not respected

[rajatparida86]

User complains about having problems with down timing an alert Internal ref:133

It is triggered for an instance (which is ok because the condition is met), but I would like to postpone fixing it so I put it to downtime for the entity.
It worked for some time but after some hours the alert is triggered again for the same entity, even that the downtime was not yet finished. So I put it to downtime again and after some hours this repeats, so I have multiple active downtimes for the same alert and same entity (currently 3 at the moment).

Any updates on this? It's happening pretty much every time we try to set a downtime.
