Yes, I've actually seen this happen again before. This is a very odd and unusual bug. The only way of fixing the bug is to un-share and re-share the project. To explain how this is legit, a new project shared will show in the featured project but not in the Shared Projects as it shows just 1 Shared Project. But accurately there are 2 of them. However, this bug shows otherwise... This is probably the first sight of this bug and glitch. So this would be considered new.
