Spacing between paragraphs is too big

Hi Ced
I have migrated a site to J4. I upgraded the template and imported it into the new site. I also exported some pages from my J3 site using PBCK and all was fine.
Now I notice the spacing between paragraphs on articles is just a little bit bigger than my old J3 site.
If I switch templates to Cassiopeia then the spacing is fine. I can't see anything on my template that would cause this.
Can you help ?
thanks

Hi
please try to disable Bootstrap in the settings (Page >> settings) and check if it works
