Bullet Time Mix Template EXTREMELY FAST

Does enyone experience this with the iOS app (most current version as well as +- previous versions) and X2 (or any other device or Android app):

The Bullet Time Mix videos coming from shotlab are extremely fast. If I choose 6 shots (or whatever number) the app always creates ~3 seconds long video with extremely fast spins and cuts. Simply useless. I have tried with countless of different bullet time shots and the result is always the same. I also noticed that the screen where I choose order of the shot always shows 0:00 long clips (see the screenshots below).

The only workaround I've found is not to export the video directly but instead continue to editing and manually adjust the speed of each bullet time clips to make it slower. Originally the app applies 16x - 4x - 16x speed ramping which creates these extremely fast and short (0,5 sec) clips.

Is there any way to make the Bullet Time Mix slower? Just like they show in the tutorial? Or what am I doing wrong?
