When zooming on image, the modal will go out of the screen

[geforce9600gt]

Hi!

I am using the plugin on this site:

https://glass.web87.hu/szolgaltatas/24/uvegkorlatok-keszitese

When you click an image, the big image will open in the gallery popup window, but it seems like, that this window will "go out of the screen", and i cant see the image description, only if i scroll down, and it gives to much zoom to the image.

I have no console errors, and i dont understand this, because i use the plugin also on this site, and there it works fine, and the code is the same. https://tetocserepemuj.gras.hu/termek/57/tondach-twist-fusioncolor-tetocserep-terrakotta

(images are on the Galéria tab)

Can someone help me please?
