Thanks for your feedback. Yes, I have found the issue on my end too. Actually, we have removed the formatting for collection description. However, you have the option to override this on your template.
Please take a new description.php
file in this location:
templates/shaper_helixultimate/html/layouts/com_easystore/collection/description.php
Then replace it with the attached file. You need to unzip the file and then replace. In the attached file, I have modified the code so that text formatting is kept as you set in the settings.
