I cant see your problem? If you want to save a favourite you do have 2 options 'Favourites' and 'Reading list' so, you can choose between the two! The gold star (black arrow) is used when you want to 'save a shortcut' to your favourites and the star with the 3 lines (red arrow) is used when you want to open your favourite, from the list that you have saved your shortcuts to.
Btw, one thing that I do have a problem consistently and when I use MS Edge, is when I want to save a 'shortcut to my favourites' (gold star) and this feature 'does not open' and/or freezes and i do have to refresh the page and/or just forget about it, as it dosen't work at all. Which is abit annoying as I have to copy the hyperlink to a notepad or word document and come back to it later and try again but, that's in extreme cases.
