Need help with saving my PDF with Bookmarks

Hello everyone,

I created with bookmarks but when I reopen the bookmarks do not appear - not sure what I am doing wrong. 

I have basically followed all the steps per Page thumbnails and bookmarks in PDFs, Adobe Acrobat and also enabled the Restore last view settings when reopening documents in Preference.

It looks great before saving but all the selections get lost after saving.

Thanks for your assistance
