Text parameter in power bin reset

Either in the upgrade to beta v5, or to v6, the background opacity of text objects that I stored in a Power Bin have been reset to zero (at least, when I drag a copy to my project's local bin). The background color opacity now reads zero, and used to be a middling value (for translucency).

A note: the SLIDER of the opacity is in the correct (old) position... but the TEXT field shows zero, and the displayed behavior matches the zero, until I drag the slider a bit.

I see something similar with Drop Shadows.

Still an issue in 17.1 as released.
