Exporting MS Word to pdf using Adobe Acrobat tab is not exporting Adobe Fonts

Hi, I am using Adobe fonts in MS Office Word and PPT. The fonts are installed for use in local apps on device and I have ensured the fonts are embedded in MS Word / PPT. The fonts appear in both applications but when I export the files to pdf using Adobe Acrobat tab (in the ribbon) the fonts are converted to Calibri in the pdf. Help?
