I am not fully understanding the problem so just some suggestions.
Start with a transparent background
File > New. Open Advanced Options; then Fill With: Transparency.
Does your image have an alpha channel? In 2.8 Colour To Alpha would add an alpha channel if there wasn't one. 2.10 does not do this automatically. In 2.10 Colour To Alpha needs two things: 1) Mode must be RGB 2) there must be an alpha channel.
