Postage service not specified on revised listing

[dotswins]

Hi, I am revising the price on a few items but one has come up with

"A postage service is not specified" and won't let me continue. There is postage specified as it was already listed. I cannot find any way past this. 

I'd rather not resist as the item has a few watchers (offers previously sent)

Any luck with this? I wondered if you could try to revise the listing on a different browser, or pc instead of a mobile? Unfortunately, this sort of error message will probably only disappear if you end & relist, but it is frustrating when you only want to adjust the price and not lose the watchers.

Try refreshing the page you`re revising, it does the same to me when i revise or sell similar & refreshing brings it back for me
