Colour Picker is "Sticking" no matter what

I can’t make the colour picker tool work just while I hold the “i” key on my keyboard. No matter what I do, pressing (or holdoing) i, changes to the colour pick tool and then I have to manually change back. How do I make it work like before? Thank you

Harmony version/build and OS would be nice to know.
What is the colour picker? ‘Alt+i’ selects the Paint Tool, just holding down ‘i’ temporally activates it. Check your keyboard shortcuts, maybe reset them if you are having issues.
