Hi Daxi, When bug reports are created they do not contain the ‘question’ tag. This tag is what shows the ‘Mark Solution’ interface. If I were to add the question tag and mark the solution, it would look strange in the ‘Issues and Bug Reporting’ section since it would be the only one that is marked as ‘Solved’. So no worries on marking the solution - Thanks for following up! ---
