Fusion Node Edits Not Showing in Edit

Hello,
I'm a new user to the Davinci 17 and am having an issue with my fusion nodes.
I currently have 7 merge nodes inline with a box in each.
[input]--[merge]--[merge]--[merge]--[merge]--[merge]--[merge]--[merge]---[output]
while I am on the fusion page I can see my boxes show up and disappear as i scrub through the timeline (or frames). But when I go back to the edit page my boxes only show up until about the 5th node and the remaining ones do not show at all. but when I go back to the fusion page I can see my adjustments fine.
also, when I'm at the point where a box should be on the edit page, if I then click on the fusion page then ALL my nodes are gone. it just shows [input]-------------[output] and none of my merges show at all.
BUT if i move my playhead / timeline back to where like merge 4 is, then go back to the fusion page, then it shows all my nodes again. (its weird..).
i've tried restarting DR17 and saving / reopening the file but it still does the same thing. Any help would be appreciated. thank you!
