[Observium] Observium frequently losts "Ignore Until" information

Hello,

I've some alerts which i want to ignore till some time. So im pressing "Ignore until".

But sometimes this information gets lost and alert appears again. In these situation "Ignore until" button in clean. I think it's have something to do with NX-OS software. Is there any workaround ?

The only workaround at this time is to exclude that devices in alert rules. What is very uncomfortable..

Thank you
