Could you provide a project archive showing this? I use transparent PNG's a lot and haven't had any problems.
The only two issues I'm aware of:
1) If you import an opaque PNG and later edit it to be transparent, Resolve will not pick up that it has an alpha channel (and you won't have the option in the Clip Properties to change the Alpha Mode since it thinks that it's still opaque). Only workaround I've found is to delete the PNG from the project and re-import it.
2) Scaling a PNG will result in dark fringes due to the way that PNG's store transparent pixels. Not a Resolve issue per-se, but annoying due to related bugs to do with compositing modes and premultiplied images (which would be the correct solution).
