Pathfinder Legacy Layout-nothing is working under Skills, ST and Other Tables

I have no idea if this will be seen or have any direct attention, but last night 1/31, All but one of my players could not get anything rolled under the section 'Skills, Saving Throws and Other Tables' to work correctly.' Nothing was using the actual calculated total skill modifier, no Saving throws were using actual bonuses. We last played December 23. No issues then; what happened? Alot of the calculations were also showing a 'floor' 13 involved. 

Hi Jim, nothing has been changed on that sheet since 2017 (I just happen to be the person that made a few bug fixes on that sheet...) The sheet seems to be working for me.  Are you still experiencing these issues?  Can you post a reproducible example that causes the error?  The more detail the better. 

So,here's where it sounds like I"m an idiot. On this last Friday night, 3 character sheets simply didn't work right. Hovering over the box to read what was going on, most of them all read a 'floor 13' and didn't draw in the correct modifiers. The guy who has spent the most time on his sheet; well, I duplicated it and re-entered everything. Now, now it all seems to work fine today.   I just want to make sure this keeps working well. we're a bunch of old grognards who find it much easier to get online to play instead of getting freedom from our families to get together. I didn't know if this was a case that I would need to purchase better membership. 

So, after replacing the 2 character sheets that weren't working...yeah, everything is back on track and working just fine!
