I have K-7 and use the Tamron 180SP f2.5 with a Tamron PKA adapter, and have not experienced this problem - all works as it should so I'm afraid it sounds to me as if there is something not quite right here.....
Sorry to bring bad news.

yes thanks- that was my main concern and they are fine which makes me think that the most important part is working - its odd that is shows the apature on the rear lcd and not on the top lcd or in the viewfinder?

The adaptor is behaving oddly and i dont know if its the camera or the adaptor or a combination of the two - When the adaptor is attached to the camera and its set on the AE setting the apature information is displayed on the rear lcd and can be adjusted and all works fine but the apature info is not displayed on the top lcd or in the viewfinder a bit like the "m" lenses display however its important to note that it looke like the lens still meters and adjusts like an A lens and you can use live view with all information shown correcty which is a big bonus with macro on the k7 - i will test it further this evening
if i attach a normal pentax "A" mf lens on the A setting apature infomation is displayed on all three screens.
I contacted the supplier who had another PKA adaptor and they got the same result with the K7 so i think its the PKA mount and K7 combination together becuase as far as i can tell both items are functioning correctly and i doubt that both PKA adaptors are faulty. (they are a very good supplier and i could get a refund if necessary)
Has anyone else had this with the K7 and PKA adaptor? - if this is the case then i will let the supplier know so thst this issue is known -i dont think its a big problem - just more of an annoyance really
