Speakers Field - Adjusting number of values for speakers to fixed-count keeps the text "Add Another Speaker" on node/add/session

Regarding Session content type for the Speaker(s) field:

Changing the Number of Values field to anything other than Unlimited takes away the button to Add Another Speaker, but the text is still visible while submitting a new session. I tested out various values and it does show the correct amount of available fields to add usernames, but the text label for the button is visible below any help text that is being used.
