"Enter" button sometimes registered multiple times

In terminal, occasionally the prompt purism@librem5:~$ comes up multiple times after a command is entered and output appears similar to this:

purism@librem5:~$ echo hello world
hello world
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$
purism@librem5:~$

I am assuming it is the virtual keyboard registering the "enter" button multiple times, even though I only pressed it once.
