Hi @h.verouden
Thanks for passing the file along! I received the same problem behavior that you described - it appears that Fusion lost track of those bodies at some point. I have logged a ticket (FUS-38028) with our development team to investigate why this may have occurred. We appreciate you bringing this to our attention!
I found that, even though Body27 and Body93 are shown in the browser, I could not find them anywhere in the model. When I turned off the design timeline, they were immediately removed from the browser. My recommendation for moving forward with this design would be to turn off the visibility of Body27 and Body93 and ignore them, as they do not seem to actually be present anywhere in the design. I played around with your file a bit and the inability to delete these bodies did not seem to cause any problems if I ignored it. This will allow you to keep the design history - if you convert the design to direct modeling mode (do not capture design history), the bodies will be removed from the browser immediately, but you will lose your design history.
Please let me know if you have any questions - I am happy to help.
