There are EEVEE issues reported by many users because EEVEE is handling the transparency a little bit strange.
IMO the default setting should be "HASHED" when importing, a value that does not cause any problems with the display of transparency.
The instructions may contain information about which transparency settings can be changed for individual objects in order to set a better but possibly unstable display/render with EEVEE.
Just a note that Alpha Hashed mode may not be the panacea you think it is. Eevee is all about compromises for speed. Because it explicitly avoids doing anything resembling ray-tracing, it is always going to have limitations.
