RGB values different in P&GD and WDP

[letsgofishing]

I've done a logo design in Photo&Graphic Designer 16.4 using CMYK colours for print.
I'm also converting the logo to RGB for web use.
In P&GD rgb values are shown as percentages not as values from 0-255 and are not correct!
In WPD 17, the colour editor shows values from 0-255 and the CMYK equivalents are correct - I've checked them in Affinity Designer.
Surely there must be a way of showing correct 0-255 values in P&GD???
