Problem with item update

I’ve noticed strange behavior with an item. Rest of similar ones are fine.
I’m using one of the last builds.
One of my old DateTime configured:

DateTime Time_update “Time update [%1$tH:%1$tM %1$td-%1$tm-%1$tY]” (gTime) { channel=“mqtt:topic:house:aaaxxxx:occupancy” [profile=“timestamp-change”]}

don’t want to change a value - like it’s hanged. When I’ve updated a name to Time_update1 it started working properly.
Had anyone noticed such behavior lately?
