Hello David,
You are quite right there is something wrong - and they would very much like to be decoded, rather than not :-)
I have come across this at 6m, 4m & 2m from time to time.
My solution is to change the WSPR base frequency to decode them and let them discover they are off frequency on the WSPR site.
Hopefully they will look at their decodes on the website (and there is probably only mine !) and discover the reason they are not being decoded (I don't know how to find out their emails, which would be better).
It is easy to make a mistake and the sooner one is aware of it then a correction can be made - if there is no information, nothing will happen.
