This is normal for the relay switched auto tuners.  Even the "standard of 
comparison" SGC 230 will stop when it reaches 2/1 SWR unless you strap it 
for 1.5/1 and then there may be times when it won't be able to get it that 
close.  The older motor driven L and C tuners were totally "variable" as 
opposed to the newer relay driven "stepped" tuners and stood a better 
chance of finding a lower SWR.

Practically speaking, 2/1 will give you about as much "on air" signal
as a perfect match, and a "radio user" (not an electronics type) will not 
notice the discrepancy anyway.  (ie: Marine shipboard use)

The reason for the new style relay driven tuners is cost, obviously. Add to 
that less maintenance.  Such is the state of the art.....
