How to align Generateblock Grid

I just open the home page, to edit, and add Grid under the Slider

Try this:

1. Create a new Page.
2. Add your slider.
3. Add the GenerateBlocks Grid.

Check if they display correctly. If so then:

4. Add the following shortcode to the page to display the Shop Loop:

[products]

If that displays correctly then use this page for your home page.
And in the Woocommerce Settings > Products remove the page you have set for your Shop page.

wow, Thank you for your valuable time and support. Everything is fine now.

You're welcome - glad to be of help.
