I SCENARIO:

MAP: with host.
default with: properties: unacknowledged only

ITEM:

active agent
logrt.count[/var/log/test.log,TEST.TEST,,,,0]
interval 30s

TRIGGER:

{logrt.count[/var/log/test.log,TEST.TEST,,,,0].last()}>0

OK --> None
PROBLEM --> Multiple
Allow Manual close --> yes

TEST:

create 2 problem items: (echo "TEST.TEST> >> /var/log/testlog.log) x2

open problem tab:

latest problem: close
older problem: ack only

Both are now listed as ACK'd.

RESULT:
On the MAP: HOST is still shown as in PROBLEM (even though problems are ack'd)

EXPECTED:
On the MAP: HOST is not in PROBLEM state (all problems are ack'd)
