Upgrade price not showing on app store

Hey guys, i am new around here. I have been using touchable 3 for a long time, though i took a break from ableton. When i came back to it yesterday i fired up touchable and learned about the new version.
However, when i go into the app store, i see the touchable upgrade and it says 43 pounds (price for both touchable 3 and pro)
I can click ‘open’ on touchable 3 so app store knows i purchased it.
Any idea whats happening here? What is the upgrade price supposed to be?

Any chance you bough the bundle? It seems like people who bought the bunde cannot purchase the bundle at a lower price.
