SFC Parallel execute twice

In the following example, I created a simple chart with a counter that starts at 0. For testing, I chose either I am using anchor A or B. In case A, counter increment once, but in case B, the counter increment twice.

Is there a workaround to fix this issue?
I’m on version 8.1.11

If anyone wants to test, here an XML export of the SFC
