PROBLEM SOLVED:
This was not a bug, but a mere user misconfiguration.
In the shortcode, the number determines the messages + settings that the form will use and the word between the quotes ” ” will determine the form content.
Without realizing this, I had copied the shortcode and ONLY changed the title and not the number.
For example:
[contact-form 1 "form 1"]
[contact-form 1 "form 2"]
[contact-form 1 "form 3"]
After changing it to the proper number, everything is working fine now.
[contact-form 1 "form 1"]
[contact-form 2 "form 2"]
[contact-form 3 "form 3"]
