trying to install latest version of smush

Hi,
I have support access turned on at the following site:
https://changingpaces.com/

I just started managing this site for a client and installed the dashboard. I noticed a version of wp smush on the site but the dashboard did not pick up on it. I want to install the latest version. Do I need to uinstall the existing version that I see (which is older)? Will that cause any issues if I uninstall and reinstall using the dashboard?
