[VE][127] the shown signs, which after the test are missed, are already there

Hello,

there are shown 12 failure for my website www.blog.ost-impuls.de

The signs, which are shown on www.w3c.org in the test of my website in red and which I
should make, they all are already there, at the described place.

Do show those red signs signs, which are missed or only, that there may be missed another
sign, which belongs to such sign, but was not found?

Do I have to put away the specified sign or do I have to add on another place in the
coloumn teir correlated sign?
