So after playing around I figured out what you were talking about. You need to point out to the Devs that the crease info on the edges isn’t displaying right away. If you select an edge and adjust the edge crease to anything, then set it back to 0, then click the filter icon in the spreadsheet the info will show up. Same with vertex crease, and both bevel weights. I think it may be by design to limit the amount of data in the spreadsheet? I don’t know if that’s the case or if it’s really a bug.
***Edit*** Just read Martians answer. So, it sounds like it is to reduce the amount of information.
