Cant make macro and need help

I tried making a target or mouse over macro for lifebloom but the game fails to put lifeblooms icon into the macro box nor can anything be dragged onto my action bars, however the macro memorizes the text.

any tips would be appreciated

Use one of the following templates. Pick the ? for the icon. You need to be out of combat when you save changes to the macro.

or

Itried the ? for an icon still doesnt work

Post the exact macro you’re using.
