Misleading road markings

On the Coryton roundabout (M4 Junction 32), lane destination markings and arrows (at location A on the attached photo) as well as overhead signage all indicate that both lanes of the circulating carriageway are to be used by vehicles taking the exit to the northbound A470, and vehicles for the A4054 or eastbound M4 should use the right lane only.
However, the dotted line separating the circulating lanes of traffic (at location B on the attached photo) has been painted such that it continues around the roundabout. This leads drivers in the left lane to believe that they can continue around the roundabout towards the A4054 and M4(E), contrary to the design intent as reflected in the other markings and signage.
I drive this route daily and frequently have to take evasive action to avoid vehicles using the lanes in a manner which is not consistent with the signage. It seems inevitable to me that an accident will occur here (if it has not already done so).
