P: Learn Tutorials using Guided Upright Tool appears to fail after tool selection

Hi,

I have noticed that some (all?) Lightroom CC Guided Tutorials involving the Geometry -> Upright Tool seem to get stuck. To reproduce:

- pick a guided tutorial such as "Fixing the Geometry of an Architectural Subject"

- "Continue" until you get the "Select the Upright Tool" prompt which points at the tool

- Click on the tool

- It functions (i.e. you can place the lines, etc.) but the Tutorial will not advance beyond this point and has to be manually clicked through with the "skip" arrows at the top

Not that big of a problem (once I'd worked out what I needed to do without the prompts and when to use the skip arrows) but, given how seemlessly everything else in these guided tutorials was working, it did catch me out!
