I think there is a small bug in the "split body" tool when using multiple splitting tools. If you select more than 1 splitting tool then edit the feature later, fusion only remembers one splitting tool.
This should be easy to re-create but I can post a file if needed:
1. start with any solid
2. create a sketch with more than 1 line
3. use split body and select 2 lines as splitting tools
4. edit the split, fusion only remembers 1 splitting tool selection
Small annoyance I know, but caused me a bit of a headache on a larger file that I couldn't figure out why everything kept breaking.
