Resulting change exist
Am new to Creo Windchill . Below image shows versions for 2D with icon for resulting change exist.

When I try to access the 2D in creo , it only opens 3.1 and can not open 3.3. But creo view opens 3.3 .
I am very confused on this workflow , can someone please guide me from basic to advanced on
1. Purpose of this symbol
2. Why four symbols
3. Why Creo opens 3.1 but not 3.3
4. How to fix this to make symbols disappear
Any videos , PDFs etc where I can get more information?
Thanks
