Prompted for update when installing a program

Why, when I try to install this, does it list the install of Ungoogle-Chromium snap package!?

Updates are installed by default when installing programs via Add/Remove Programs (aka Pamac). Anything less will leave you in an unsupported partial upgrade state. See System maintenance - ArchWiki

I did previously uninstall the flatpak ungoogled-chromium package a while ago…I then installed a non-flatpak version of UG that works fine.
