Cannot save process in Modeler

Hi, I am currently new to BPM and I tried to make a simple process in Activiti Modeler. However when I try to save the process, it shows this:

"Something went wrong when trying to save your diagram. Please try again. If the problem resides, please contact the Signavio Support via the envelope symbol in the toolbar."

I don't see any envelope symbol in the toolbar in the modeler and the threads that I read don't really help me so I thought I might ask for some help from the experienced ones in this forum. Thank you for your time.
