The slow start spinning wheel is definitely related to the Times counter.
The question is "how the numbers got so big"? 333 instead of 33. Many of my charts seem to have this. (I hadn't noticed because there is only room for 2 digits.)
I am using 2.8 and I think most of these charts were written with it.
Perhaps when pressing the arrow key a certain way it will add a digit or could it be from the editing process? Is there any way to set the Times Counter in the edit process?

I write charts on many devices also , so perhaps it happened in the transfer process.
