I only use TL for initial lists.

Maybe - look at 'Listing Activity' for the item. If it isn't there (it probably is unless you synchronize [sic] regularly), then look at 'Ended'? The other option anyway.

Then select 'relist' or 'sell similar'.

Did you originally schedule the listing? That might be the issue - untick the scheduled time option.

Other than that, I can't think of anything.
