AutoVoice Optional Named Group Regex Not Working

I am having a problem with some AutoVoice regex where I would like to make a named group optional. I currently have two profiles that are working for this, but I would ideally like them combined.

Current regex:
(?<action>lock|unlock|open|close) (?<door>all|front|garage) doors?
(?<action>lock|unlock|open|close) (?<verb1>the|my|our) (?<door>all|front|garage) doors?

All of the current regex works, I just want it to be a single profile. It will recognize:
lock all doors
lock front door
lock my garage door
unlock the front door

This is what I think should work:
(?<action>lock|unlock|open|close) (?<verb1>the|my|our)? (?<door>all|front|garage) doors?

The ? after it is not allowing it to be optional, but otherwise still seems to work (if verb1 is not omitted). If this needs to always be multiple profiles, at least it works. But the number of profiles could be high depending on how many optional groups I am trying to use.

 

I've added an extra question mark to make the second space optional. This seemed better to me than adding a space to the end of each word. This is now working, thanks.

Working regex: (?<action>lock|unlock|open|close) (?<verb1>the|my|our)? ?(?<door>all|front|garage) doors?
