Is there a way to suppress the tag created by the converter

@chbaruwa ,

Are you referring to the https://1password.community/discussion/101693/moving-to-1password-from-another-password-manager ?

Regardless, this tag is something created by 1Password upon import. It helps you keep tabs on what items you just imported, so that you can distinguish them from other items already existing in the vault.

You can select all your items, and right click that tag in the sidebar and then select Delete to remove that tag.
