seas_buffer = 0 flags all records

[TheTams]

I have a GBIF download on which I am running coordinate cleaner. I tried running different seas_buffer distances to check my understanding of how it worked. The parameters for seas_buffer produce the number of flagged records below. The first three behave as expected, where a larger buffer results in fewer results flagged (marked as within the sea polygons), and the smaller the buffer the more are flagged.

seas_buffer = 2000 44204 seas_buffer = 5000 25969 seas_buffer = -2000 137447

This last one, where I tired a seas_buffer of 0, resulted in all of my occurrences being flagged. While of course, one would just not run the seas_buffer if you don't want one, this seemed like unexpected behaviour.
