For protection purposes, I use a convex clock glass in a filter holder. It eliminates the ghosts at the expense of a slight loss of quality. I seem to remember in the good old 1960s you could buy convex 1A (uv) filters, or did I imagine it. Or remove filter and risk your lens!
If you have a problem with several lenses, and the camera is still under warranty, I'd get the sample pictures on an SD card (also adding pics of a neutral grey/whitish wall at varying apertures for reference) to take with you to the shop, and get it serviced there.
