Blocs - OctoberCMS

Hi people,

Just trying out Blocsapp… Can be amazing.
Also testing October CMS, can advise this CMS to everyone.

I have made a simple site in Blocs and saved as a October CMS files.
Works as expected. Now I have installed the files in October CMS and selected the template.
Works ok! But when I change the (content) text via a WYSIWYG CK editor the font styles form the site are changed.

With TinyMCE editor it look to work.

Anybody experience with Blocs and October CMS?
