Auto Merge not processing PR's

I've installed auto-merge today and filled out the auto-merge.yml file, I've added it to the .github folder. However, PR's are not being merged, despite them meeting the requirements. My auto-merge.yml is as follows (I've removed the comments):

minApprovals:
  MEMBER: 2
  COLLABORATOR: 2

maxRequestedChanges:
  COLLABORATOR: 0
  MEMBER: 0

updateBranch: true
deleteBranchAfterMerge: true
mergeMethod: squash
mergeCommitMessage: |
  {title} (#{number})

  {body}
requiredBaseBranches:
  - qa

blockingLabels:
  - blocked

requiredLabels:
  - merge

A PR is ready to be merged and meets the requirements, but nothing happens:

Why isn't it being merged?

We are in the same situation with a stock standard configuration file.

Is there something we are missing in the configuration?

minApprovals:
  MEMBER: 1

updateBranch: true

deleteBranchAfterMerge: true

mergeMethod: squash

requiredBaseBranches:
- develop

blockingLabels:
- blocked

blockingTitleRegex: '\bwip\b'
blockingBodyRegex: '\bDo not merge\b'

Mine seem to run after 1 approval even though we require 2 and then it won't run the check again after the second approval.
