Instances unnecessarily take variables from other variants

There is a bug in Figma.
I have a component, e.g. a button. It has two variants. One variant has a padding of e.g. 4px and the other has a padding of e.g. 8px. (variables)

If I switch between the variants in the instance, the second variant takes the padding from the first one.

The same error sometimes occurs with corner radius. This is a random error that sometimes occurs.

Is this error already known here?
