Impossible to Centralize HTML Codes

I started using your theme AzonBooster recently. While I’m already a fan of this theme and plan to check out your pro themes, I’m facing a problem with it.

All images (added using HTML codes) that were previously centralized are now aligned to the left. I noticed all HTML codes were automatically modified whenever I tried to . <div style=”text-align: center”> now appeared as <div style=”text-align: center;”> (please see the screenshot here https://prnt.sc/m4h2j1).

All images are aligned to the left but are centralized when I switch from AzonBooster to another theme.

Would be great if this glitch can be fixed.
