Framemaker 2017 does not convert anchored frames correctly to html 5

I have document in Framemaker 2017 Unstructured.

I convert it to HTML 5 using the publish feature

Anchored graphics which only holds one image, converts correctly

Anchored frames which hold both an image AND some text boxes do not convert at all. The conversion process merely leaves blank spaces.

How can I make it work, so these anchored frames which hold text AND graphics convert correctly?

Best regards

Bjørn
