You have a good chance of getting rid of the extra entries with just updating the grub config.
If you want a really easy way to do it, install grub-customizer, run it as root, there you can graphically explore the entries if some were not cleaned properly during uninstall, then hit 'Save', which saves grub.cfg and runs grub-mkconfig.
A harder way is to look by yourself in /lib/modules (with care, double check what is installed/what is not) if there are any stray kernel cfg's, then run grub-mkconfig -o /boot/grub/grub.cfg
