EasyBlog can't see subtitles anymore

Hello Everyone,

I realized that even if I put subtitle blocks (f.e. H4) into my blogpost they don't appear anymore in the blog listing page.

But they are shown correctly in the blog itself.

I guess I made somewhere a setting disabling this.
But older blogs where I used subtitles appear correct in the listing.

Can u help me please?

Tnx a lot for you kind help in advance and
Best regards

Alp
