I've got a trigger name that gets evaluated differently in 'Last 20 issues' and 'Status of triggers'.

The trigger is configured like that:
Name: Expect more than {ITEM.VALUE1} foo processes
Expression: {host.example.com:proc.num[foo,root].last(0)}<1

In 'Status of triggers' it is evaluated to:
Expect more than 0 foo processes

In 'Last 20 issues' it is evaluated to:
Expect more than 1 foo processes

The value of the corresponding item is 0.
Other macros might be affected too but I noticed it only for this macro yet.
