Pet Action Hotbar Doesn't Respond on PS4

Hi,

I just tried the new trial (The Steps of Faith) today and I noticed that my pet action hotbar doesn't respond to button presses. When I click on a cannon, the pet action hotbar will pop up correctly. However, whenever I hold down R2 and press the associated button (e.g., O), nothing happens. I also noticed that just clicking on the cannon again will trigger one of the actions, but this leaves me with the ability to only trigger one of the three actions.
