Hi @yvrmark,
I’m sorry for any disruption caused following the recent updates.
There is a Screen Options pulldown at the top of that screen – you can use this to determine which columns you wish to show and hide.
We also removed a component called Advanced Post Manager, which previously shipped as a part of Events Calendar PRO and helped to manage this screen – however it is still available as a separate plugin you can install if you’d like (which may restore something closer to what you used to have in place).
Do either of those ideas help here?
