Noob question: How to reset issues

[IGuessImTheITGuy]

We have a large number of switches from an old vendor that tend to overheat, and I finally found the OID for temperature. Because some of these are in a stack, there's a huge OR statement for each potential switch in the stack. It also reports as a "High" severity.
The reporting works, the notifications work, but some of these temp issues are transient, and these high severity issues don't auto-clear like my "Average" issues. I put a recovery expression in, but it's still not working.

How do I have High severity transient issues auto-resolve or reset?

severity shouldn't matter, it's probably a logic error. Have any items in the test gone unsupported? Check latest data to make sure Zabbix has seen the cool down :-)

I do have some unsupported items (depending on number of switches in the stack), but the latest data is showing proper temperature.

I'll post the logic when I get back to the office.

Here's the logic:
For the trigger:

{Template Switch Temperature - Avaya:InternalTemp1.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp2.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp3.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp4.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp5.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp6.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp7.last()}>45 
or {Template Switch Temperature - Avaya:InternalTemp8.last()}>45

and again, there might not be 8 in the stack.

Recovery:

{Template Switch Temperature - Avaya:InternalTemp1.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp2.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp3.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp4.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp5.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp6.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp7.last()}<45 
 and {Template Switch Temperature - Avaya:InternalTemp8.last()}<45

Recovery was done after attempts to have it autocorrect failed.
