May you please take a look on https://www.openstreetmap.org/changeset/56049498 ?
A user has tried to map islands in the mouth of the Lawa river (example), but tagged all of them as waterway=river.
I can’t retag and convert them into “inner” elements because any “outer” riverbank way is missing.
Best wishes
Do you know any mapper from Suriname? You could contact him.

Always start by discussing the changeset. Perhaps the mapper is unfamiliar with other tags, and a little bit of advice is all they need.
