Shortcodes are not displayed as shown in the example

I use Shortcodes A-Z Listing và [pwb-all-brands per_page=”10″ image_size=”thumbnail” hide_empty=”true” order_by=”name” order=”ASC” title_position=”none”]

But when displayed, it is not on the normal page but in a separate frame, and must be dragged left and right to see all the brands.

For A-Z Listing, the alphabetical list is not displayed in a straight row but displayed diagonally.

I took a screenshot, please help me find a way to fix it.

Thank so much!
