Problem with gallery mode – changes do not apply according to the function

Hello,

After changing my theme design I’ve been experiencing some issues with Jetpack gallery mode.

When I apply photo size and gallery type it does not show up according to what I choose.

For example I tried to change “square tiles” gallery image size, but no matter what size I choose (thumbnail, medium or large), photos stays the same size.

Also the galleries are not aligned according to the area of paragraph

Some examples:

I hope someone could help me to fix this.
