Strange behaviour of blog columns

Elements CMS
1

Hi there,

just recognised something regarding the blogs columns which looks strange. I can set in the collection the number of columns. In my below screenshot 4. So far so good. From the “lg” breakpoint upwards its 4 columns now. But when I go smaller, it changes to 1 column no matter what I set in the columns (see 2nd screenshot). Is this a bug?

I found the error after posting here. The Container in the Collection had some own settings which are conflicting.
