A screenshot, something like the one below, is best, showing the problem but also the tools, FG/BG colour and layers.
Just for reference:
Without an alpha-channel (transparency), cutting a selection will use the background (BG) colour, which could be grey.
With an alpha-channel, The representation of transparency depends on Gimp settings.
In Edit -> Preferences -> Display there are various options, with checker pattern, solid.
Then of course with a layer under, you see whatever is there, which could be a plain grey layer.
