So sorry no one has come along to answer your questions yet. Many peeps are absent on Sunday, I'd say that's likely why. I have shared your thread on another thread so hopefully we'll get you some help soon.:fl
I'm not sure what to tell you but hopefully @WVduckchick or @casportpony or @Pyxis are around and can answer your questions and help you get her over this! :fl
Best wishes to you! :hugs
