More than one "Single Product Templates" in same Category

I have a problem and I can’t make any progress.

I have several woocommerce “single product templates” for different categories.

This works wonderfully via the “Conditions”.

In one of the categories, I would like a separate “single product template” for each article manufacturer.

In the conditions I set it as follows:

Post type: products
Terms: Category
Terms: Item property “manufacturer”

Articles are also assigned to the manufacturer in the category.

Unfortunately that doesn’t work, the template that was created first is always used, regardless of the condition.

What mistake am I making that it doesn’t work?

best regards, daniel
