How do you save a Hotlap preset with the Hotlap App ?

I wanted to catch my times on a rally course in Utah. I used the Hotlapping App to create a course around the map and then tried to save it.
Sadly, i cant do that because it only says "Click to Rename" but in the Field where you need to save it says "no file"
Is that a bug or am i missing something ?

 

Have you clicked the floppy drive icon to select a file?
sorry if that's obvious i havent used this app.

 

Sorry for the late Reply, only got now back on my PC.
Yes, i basicly clicked and tried everything.
It might be a mod messing me up so i will deactivate them and see if it works then.
