"ankihub_protect::All" is not protecting all my cards

Hello,

The tag is case-sensitive. Are you sure you are using this exact tag? “AnkiHub_Protect::All”

If it has a lower-case letter at the start of the word, it will not work

Ankihub_protect::All = will not work
Ankihub_Protect:All = will not work because the H in ankihub is not capitalized
AnkiHub_Protect::All = will work
