A small number of products has multiple mark symbols. Currently only one is supported.

An example is Dr. Bronner's Shikakai soap teatree with ingredients:

and

Water, groentenª¹ 26,3% (broccoli 17,2%, erwt 2,5%, prei, ui 2,6%, spinazie), aardappelª¹, ROOMª 5,9%, maïszetmeelª, raapzaadolieª, zout, rietsuikerª, gistextract, nootmuskaatª, aroma, ª afkomstig van gecontroleerde biologische landbouw., ¹op duurzame wijze geteeld.

A repitition of a single character in a mark would still be one mark, when there are different marks after each other, they are different. Then there is the bracketed notation for multiple marks (let's limit this to two note marks, as we'd need examples, e.g. would it be * (***) (****) or * (***, ****) or (*, ***, ****)?)
