In videos playlist in week 1 of foundation of DS, complete and continue option is missing

In my playlist of course in week 1, complete and continue option is not showing.
should I pay concern to it or I shall continue with the same (without marking continue to the videos ).

It happens sometimes, just make sure that the tick mark on the bullets present at left side appears.
Maybe try changing your browser or try Incognito mode.

thanks ishvinder now it is working but only in chrome not in brave and firefox
