Existing labels get removed even with `sync-labels: false`

[akihironitta]

A possible misbehaviour

Existing labels get removed even configured with:

sync-labels: false  # which is the default

In our repository, we see that the labeler removes an existing label right after the label gets added to an PR by one of our maintainers as observed in https://github.com/Lightning-AI/lightning/pull/13703.

Our configuration

• labeler caller: https://github.com/Lightning-AI/lightning/blob/35ec79ad1f75790767a6857637c9bbe052e47b58/.github/workflows/labeler.yml
• labeler filter config: https://github.com/Lightning-AI/lightning/blob/35ec79ad1f75790767a6857637c9bbe052e47b58/.github/labeler.yml#L1-L3

Additional context

There's a similar comment in #365 authored by @1bberto

for some reason the labels are not being added to the PR and are also being removed when I add the labels manually
