weird behaviour of archive view when inserting Meow gallery

Hi,

I’m currently in the process of switching from Nextgen to Meow (primarily because of the LR plugin ;)). So I’m reworking m posts (blog), and noticed some strange behaviour. My posts usually look like this (I’m a festival photographer)

title
date
some teaser text
a “more” block
some text about a band
the gallery of that band
and so on…

in the archive view, you typically see the featured image, and everything until the “read more” link.
However, as soon as I insert a Meow gallery into the post, that gallery is the only thing besides the tile shown, also no “read more” link.

I left the link above intentionally broken, so it can be seen
