Tutor LMS on Ocean WP Theme: issue with typography character size

I recently switched from Hello Theme to Ocean and the passage went smoothly except for the pages generated with Tutor LMS plugin. In particular, the issue is about the size of the characters being very tiny. I tried editing the general typography settings on the theme and looking for settings inside the plugin itself, but there is no such thing as typography. The only thing that has worked is writing a personalised html in the editor for the single pages of the courses, but this won't solve the problem for generated texts I have no control over, like navigation buttons, descriptive titles, etc. Any idea why this is happening? Thank you
