I have delineated a shoreline and created an offset "buffer" of 75' and 250'. When projected onto the screen it appears as though a computation error has occurred and the buffers extend onto the left of the baseline. What may have caused this? I have edited the buffer nodes after the fact to trim out these shapes but would like to know for future reference. enter image description here

    Can you share the shoreline data?

    It's a bit tricky to tell which layer is which, because you have two buffer layers with the same name and identical styling.
