Red Raspberries

I ordered the D.T.Brown - Long Cropping Raspberry Collection that consists of  6 canes each of the following three varieties:

Malling Juno (early) - Tasting the first raspberries of the season is always a treat and Malling Juno is one of the best on the market. The medium to large berries have a firm texture and a deliciously sweet flavour - just perfect for eating fresh. The spine-free canes are leafy, easy to handle and prune and, the fruits are well presented, so picking is easy too! Cropping from early to late June (even earlier if grown under cover), plants are known to have excellent disease resistance as well. Bred by East Malling Research.

Tulameen Pearl (mid) - Tulameen Pearl is far superior to the popular Tulameen which D.T Brown have sold in the past. They think this vigorous new strain is a real find and you are sure to agree it’s a winner. It has a high yield with berries which are larger and brighter and the fruit is firmer so keeps better once picked, though we doubt these fruits will last long in any household with a taste like this! 

Polka (late) - A multi-award winner at the National Fruit Show, Polka has exceptional fruit quality and the large, medium red berries are full of fragrant zesty flavour. Bred in Poland with Autumn Bliss as one of its parents, the virtually spine-free raspberry canes will yield double the crop of Autumn Bliss and Polka crops up to 2 weeks earlier, from late July to October. Polka even grows well on less desirable soils. 

Due to an error in dispatch I received were Autumn Treasure and not Polka. D.T Brown kindly sent the Polka so I've ended up with four beds of Raspberries.  

Autumn Treasure (late) - Bred at the world renowned East Malling Research centre, is set to be the benchmark for home gardeners. This quality primocane has a high disease resistance to root rot, wilt and powdery mildew, and crops well even on poorer ground. It gives an exceptional yield of very attractive, large, firm berries from August to October and the fruit stands wet weather very well. the flavour is very good indeed - not as acid as Autumn Bliss. Spine free canes.
 

Now I really don't why the first two red raspberries have appeared on the Autumn Treasure which is supposed to be a late Raspberry that should harvest between August and October?  

There are green raspberries forming on all the varieties other than the Polka at the moment. I am a little confused and it appears so are the raspberries!
