VueCarousel-slides missing on some dates

[Morgenkaff]

There is some kind of problem where the times disappear. An example is on the demo on Jan 4th.
Here's some screendumps of the problem.

It only happens for dates in the next year, and only on some.
I'm not really able to figure out, where in the code the functions behind the VueCarousel is. But if you will point me in the right direction, I'll take a look at it.
