I have a right-of-way polygon (ROW) that I generated a 3-foot buffer with the intention of selecting all parcels within this buffer. When using a SpatialFilter in FME not all of the parcels with in this buffer are selected as they should be. A sample of the parcel and buffer data is attached and the Parcel with OBJECTID 85 does not select. When using the same data in ArcGIS Desktop the parcel does select. Note, the buffer is created at 3 feet, a larger buffer results in false positive results.
I also noted that when viewing the data in ArcGIS Desktop and FME Data Inspector the parcel is clearly within the ROW buffer; however, when viewed in the Visual Preview in FME desktop, the parcel is not within the buffer. Screen shots below of the same area in all three viewers.

Note the parcel crossing the ROW buffer when view in FME Visual Preview and not in ArcGIS desktop or FME Data Inspector. Sample data demonstrates the issue for one parcel (OBJECTID 85). Sample workspace, GDB and MXD (10.8) included in the ZIP file.
