MinMax with variable Product, not working

Hello

i am trying to use Min/Max for Variable Products.

I set the minimum amount and the default amount to 5.

However, when i test it, the minimum/default amount is not applied to the product. It still shows 1 as default value and i can even take just 1 to my cart instead of 5.

When i use the Min/Max Setting for the entire product, it works well. It only doesnt work for the variable products.

Here are all my setting, they seem all correct to me:

I created a staging environment, if you want to have a look at it:
