Magento 2.3.3 Tax calculation wrong

I have a german store, therefore we must calculate 19% tax on every product. I’ve setup every settings to ensure that would happen, but for any reason only 15.97% are calculated. Please take a look at the images below, maybe you guys find something i havent seen…

Product price is 100€, so the calculated tax should be 19€, but 15.97€ are displayed as tax on the order summary.

EDIT

After taking a closer look at the tax rate of 15.97 I saw a pattern there, if you substract 19% of 19 you will get 15.966 which gehts rounded by magento to 15.97, so my tax rate gets taxed for some reason, anyone know how to fix it?
