Seems like your theme created with Type = 1 (Virtual). So your layout file not overriding.

Check your database table "theme". If your theme type is set to 1(virtual) or 2(staging) set it to 1(physical).

YOu can check theme types in details here: Magento 2 - Theme Type 0:physical, 1:virtual, 2:staging. When to use?

Hope this helps!
