Meta Tag and Title modules have issues with Taxonomy field saving

I’m having an issue where, when metatag is enabled, and the description field inside taxonomies has been ‘replaced’ with a field instance, any content that is entered into the description field does not store on save. This problem has been tested on a fresh drupal 7 install, as well, the metatag module has been updated to the latest version.
To replicate this issue:
⁃ enable Title module
⁃ enable Metatag module
⁃ create a taxonomy vocabulary or edit an existing one - hit the replace option for the description field
⁃ add or edit a term, entering text into the description field
⁃ save the term and go back into the edit term screen to see that the description field is empty
