[BUG] Numbers Incorrectly Cast As Strings

[7RedViolin]

When using the sigma rule

title: Test Rule for System Process
status: test
logsource:
    category: process_creation
detection:
    sel:
        ProcessId: 4
    condition: sel

the resulting query is dataset=xdr_data | filter (event_type = ENUM.PROCESS and event_sub_type = ENUM.PROCESS_START) and (action_process_os_pid = "4")

This then throws the error Value 4 for operator = is invalid. expected number but received string
