Grid reorders in a single column after updating the number of buttons in the container.

[dovbaeb]

I have a list of buttons that I can sort by tags, so only a few appear after I selected a tag. When I do this, the remaining buttons get rearranged in a single column, on the left.
But if the very first button of the grid is one of the remaining buttons after I selected a tag, the grid keeps its 5 columns layout.

The css is not at fault
here's the rest of the code

I also use lozad.

Here are the libraries I use :

Thank you very much
