Last October, I put the similar A743 kit on my A3S. I have not seen  
this "narrowing" of 20m. The 20m SWR curves are much the same as before.

The 40m has a rather narrow SWR bandwidth by itself, but it has  
worked very well for me -- better than any 40m antenna I could put  
up, mainly because my highest support is limited to my 15m tower, on  
which the A3S resides.
