Not sure what the problem is, but may try A)Relogging/Restarting and B)Different items. If it's a story quest, please make that clear. And you will want to submit a ticket via support, if it's still an issue.
For a more active response, you may try the discord chat, cuz the forums are fairly slow for mabi pro.
