Icinga2 dashboard showing incorrect down time

Hello Team,

My ICINGA2 dashboard under Host Problem is somehow showing date Apr 17 for all the hosts. Same is with Service Problems also as shown below.

Configuration - Icinga Web 2 Version - 2.7.3 & Director 1.6.2

Additionally - When I try to deploy some changes the dashboard went blank sometimes and under Deployment there is message that the last deployment is pending. The message remains forever until I redeploy the changes which in turn bring back the dashboard but with notifications of all the current Host & Service problems.

Could someone please advise where should I start to look into the issue?
