How to discard unwanted changes

[Rccou]

Hi

I have a problem with a R80.30 cluster. I had made some changes to interfaces which seem to have caused some topology changes to other interfaces. I have also made other simple policy changes. 

I have published these changes but the install fails each time with various errors about topology, interfaces etc.

In total I have over 95 changes from 4 sessions that i want to simply discard and forget about and not to install.

I have followed the advice in this link:

https://community.checkpoint.com/t5/Policy-Management/R80-Change-Control-A-Visual-Guide/td-p/39702

and reverted to a previous known version but the 95 pending changes still seem to be pending installation and i don't know how to get rid of them.

How is this done?

i reverted to an earlier version but the pending changes are still there.I'm stuck with these changes in the install queue

no option to discard
