Wrens nests

As there is so much expertise out there, may I ask a question that has been puzzling me for ages?

We have a resident wren in our garden which has given us much joy and tears over the last 5 years (see my post about all 6 babies being taken by ? magpies)

Do wrens build several nests? Our wren can be seen building at least 4 nests around the garden, but only one ever seems to get used by the female. Is this usual behaviour?

Thanks
