What counts as a Limited release?

For Lockjaw (2025), the US release shows as a full nationwide release on August 8. However, as far as I can tell, this is the release schedule (from the distribution studio's official Instagram): https://www.instagram.com/p/DboS5MrAalY/?img_index=1

Sure looks like a limited release, playing in about eight theaters before the digital release on September 8, but IMDb rejected my attempt to change the August 8 release to "limited" with a reason of "Unable to verify." I provided that Instagram link above. What else would verify this?
