Pantone Swatch turning black in Edit Colours
Hello, i'm changing some colours in some documents i'm about to send to print and changing the colours from ones i've just picked on the screen into specified pantones. I'm pasting swatches into each document to then select all on active artboard - edit colours - recolour artwork (under prominent colours the colours look broadly correct at this stage) - advanced options - colour picker for each colour and choose the pantone swatch to convert to.
Then when i go back to verify if the colours are correct i edit colours - recolour artwork and under prominent colours there are three colours that look the same as those i've chosen, plus an extra BLACK.
The black doesn't appear in the colour picker screen but i can't remove it from prominent colours.
I understand Pantone and Adobe have had a bit of a separation and that there are bugs associated. Does anyone know the fix please?
My documents are using white (ffffff) Pantone 2188c Pantone 7590c
Thank you very much for any help
