I still think you are picking up additional BBC transmitters during weather when reception is improved. The problem with this is that it will cause BBC stations to disappear as by and large, they use the same tuning parameters nationally. DAB receivers do not like this when signal strengths are similar.
An easy way to check is to do a rescan - do any unfamiliar stations appear? When this was happening to me I was getting Kent and Surrey DAB stations from Suffolk.
Try using it in part of the house with poor reception or wind in the aerial and see what happens. You need to try reducing the signal, not improving it.
