Build a Visual & Add to Visual Buttons Missing

Hi there!

I hope you guys are doing well and my query might sound a bit dumb. I have been using power BI since a month and half but all of a sudden my buttons for "Build a Visual & Add to Visual Buttons" went missing which are showing in the top right side of every visual/graph in report page. Here is the screenshot attached with blue box to make sense. Please let me know to how I can make them appear again on my page and work comfortably. 

Regards!
