Steps to reproduce:

1. On a host, create a macro: {$SENTRY_WARNING_THRESHOLD} with value 10
2. On that same host, create a second macro: {$SENTRY_WARNING_THRESHOLD:"default-asp"} with value 15
3. Create a discovery rule with 2 LLD macros #PROJECTNAME and #PROJECTSLUG, with the following item prototype:
   • Name: {#PROJECTNAME}: warning threshold
   • Type: Script
   • Key: sentry.project_warning_threshold{#PROJECTSLUG}
   • Parameters:
     • threshold: {#SENTRY.WARNING_THRESHOLD:"{#PROJECTSLUG}"}
   • Script:
     • console.warn(value);
       var obj = JSON.parse(value);
       return obj.threshold * ((new Date()).getHours() + 1);

Result:
When testing, the correct value is returned:

Note that the macro value has been prepopulated correctly.

The server log shows:

1975570:20240312:190835.064 {"threshold":"15"} 

However, Execute now the item and the server logs the wrong value:

1975549:20240312:190845.067 {"threshold":"10"} 

Expected:
The server should receive 15 as the value in both cases. At the very least, testing and execution should result in the same value.
