Tablet view offset to right only on homepage, other views correct/as expected

Hi there and thank you in advance for your support.

Have built a site using the Astra theme, though the issue occurs with Twenty Twenty, Responsive, and any other theme used to preview. Built the Home page using the WordPress visual editor and blocks.

Site looks as expected when using the Desktop and or Mobile (phone) views under Appearance > Customize. However, the Tablet view (confirmed using Blue Tree/Screenfly site test) is way off. The text and column blocks are shifted to the right, causing rows to break, while some headers remain centered—a mess. Here’s a screenshot: https://snipboard.io/RbEqkH.jpg

Not sure when or how this view went awry, as it had not been checked for a long while, but did use Health Check to disable plugins to no avail. Tablet view still caused a shift in Home page elements with everything disabled.

Did notice at Blue Tree/Screenfly site that the tablet view did look as expected when viewed using the settings for iPad Pro, Samsung Galaxy Tab 10, and Chromebook Pixel, if that means anything.

Something to do with breakpoints? Poor use of blocks? Would appreciate any suggestions or assistance on how to fix this.

Thanks again.
