FullWidth Master Slider doesn't work

Hello,
i installed the master slider 2.7 together with WordPress 4.4.2 and use a fullwidth-slider and a normal slider, they are working very well.
then comes the update for wordpress 4.5.1 and for master slider version 2.7.1
now, the fullwidth Slider does not work. i think since the updates.
i turned all plugins off with the same effect. i tested the fullwidth slider with an other template/installation, but it’s the same problem.

have somebody else such problems and perhaps a solution?

thanks,
Jens
