AI CC 2020 (Apple Mac): I have noticed a bug - a serious one that stops me from working. If I make a shape with a fill of (for example) 30% I would expect the next shape to retain that percentage of fill - which it always has done (I'm a very experienced user of Illustrator and use this feature all the time). Now I find that each new shape reverts to 100% fill which is totally unworkable as I draw by building up layer upon layer of opacity fills. The advisor online checked with his versions of AI CC 2020 and found the same issue - which is really strange. My old CS5 on an older Mac works absolutely perfectly. Please look into this and advise. Perhaps is a preference or setting that need checking somewhere - but I can't find it! Thanks
