Why Does One Of My Scenes Force Me To Double Tap?

[My-kl]

One of my scenes that has tap and long tap functions (on the same element) has a problem: if I use the long tap option I need to double tap any other element to get a response. It wasn't always like this. One of my other scenes with tap and long tap (also on the same element) doesn't cause this issue. Attached is the description of the problem project. Did I change a setting that I can't find?
