edit woocommerce "my account menu navigation links" (dashboard, edit address,..

the navigation links for the Woocommerce my account menu items dashboard, edit address, edit account, ecc show into the wrong direction (example: mysite.com/my-account-2/edit-address). I can find no place to edit them. I am not familiar with HTML and other, just want to find out where the individual links can be changed to the right URL (correct: mysite.com/my-account/edit-address.There is no specific Woocommerce Customer Menu i could edit.

I have inserted a YIT Woocommerce login into the Header Sidebar and after login the menu items there show the right URL (for example mysite.com/my-account/edit-address). When I wanto to use the navigation Menu that Woocommerce offers after login, the link shows the wrong URL (for example: mysite.com/my-account-2/edit adress). Where can i change the mapping to “my-account/edit-address”?
