Answer 1

Firstly, you have a grid there of 9 columns, put 12.
That is, so that the class is col-md-12, most likely there may be such an add-on in the theme settings.
Secondly, get rid of this misunderstanding:
You don't need to display the block as a table.
Thirdly, add to the marked class the properties marked accordingly.

display: flex;
justify-content: center
