After recent update, every time I duplicate an item I get a swatch conflict popup

Hello!

After a recent Illustrator update I noticed that everytime I duplicate an element on my artboard with Ctrl+C - Ctrl+V, I get a pop-up window telling me there is a swatch conflict (merge or add swatches). I use global colours on the duplicated elements and it doesn't make sense why this pop-up appears. I understand if I bring something from a different document, but duplicating elements in the same document I do a lot and having to click that pop-up every single time is so annoying.

I imagine this is a bug, but maybe there's something that can be done in the meantime, until the update that will hopefully fix this.

Thanks,

Liviu
