Settings Tax & Calculation Rule in VirtueMart 3.0.18
If I add a rule for the product categories:
default price changes only in this category (ok)
If I add the rule, and I not choose a product category:
Prices will change everywhere (bug)
https://docs.virtuemart.net/manual/general-concepts/209-general.html
I assume that you have prices set to apply default rules
A default rule is one that is not restricted - this is the base behaviour
Please read the documentation before posting as a "bug"

Now I understand. Thanks for the clarification.
