Cutom Stylesheets not beeing updated

Summary:

Hi there,

I'm acutally creating some custom stylesheets. They are refering to other custom stylesheets as wll, which is working well. But when I upload a new xml version during testing, it's not becoming effective when sending out a tender. I have to delete all custom stylesheet contents and re-create and re-upload them until my changes take effect. To do so, I have to remove all references in the stylesheet profiles as well, and change them back to the custom stylesheet contents after my update has been uploaded. This is very frustrating..

Do you have any idea what I'm doing wrong? I believe thats not as expected..
