Ticket prices calculated wrong – Bug?

I have just set up a testing environment with a non-commercial license that does not allow further support so I’m asking here.

Normally I write themes from the ground up, this time its a non-commercial project that requires fast results instead of the cleanest codebase. Also I ever wanted to try out how these block-themes work, I do use Astra. No custom templates or hooks at this point.

I have set up an event, with the price of 10€. On the frontend it shows 1000€, when choosing one ticket it shows the total of 0.01€ – in the final woocommerce checkout the price is correct though.

I have not looked deeper into the code, pretty sure it can be solved on my side. But it might be a strange experience to others.
