Magento – Admin/Backend has wrong currency separator

we are using the Magento 2.4.5-p1 version.
On frontend we have the correct currency separator for Germany. eg. 149,99 €.
But on admin/backend we have on price input field 149.99.
Any idea, how to change this? Its a small issue, but sometimes on editing products its annoying.
