Changing undo preferences does nothing



Hi, Reaper seems to save everything I do in the undo memory, even things like moving to previous or next transient. This means if I want to undo an actual proper change I've made, maybe deleting an item, I have to wade through fifty undo points because of all the subsequent times I've moved to a transient or selected an item. I just want major things to show up in undo, not little things like moving to a transient, which can be easily undone by moving to the previous or next transient. I've gone into general preferences and unticked all the undo options, just out of curiosity, but nothing changes, I still get things like moving to previous or next transient being saved as an undo point. Is there anyway of stopping this from happening? Thanks.
