Brave browswer sidebar (PC, Win10)

Hello,

I have recently cleared the cookies on my Brave browser and couldn’t help but notice some strange behaviour in terms of the sidebar. The icons of wesbsites either do not reapear or become discoloured (screenshot below). I understand that this is because of the cookies, but my problem is that some icons become normal upon visiting the website again, and yet some remain just the first letter or discoloured. Not a major issue, but looks a bit ugly and the only way to fix this that I have found is to remove the websites from the sidebar and readd them.

At first I thought that this could be the issue, but it seems not:

Disregard my post, everything seems to be working as intended.
