I had this problem a number of days ago. I emailed support. Took a couple days but they fixed it. I think its a system glitch. Seems that any editing of original price or description doesn't change in a regular search, but will show when someone actually views the item. I hope Etsy gets this fixed soon.
I just reported this thread to have it moved to the Bugs section of the Forums, so hopefully admin will help you there.
There is a link to contact Etsy Support at the bottom of the Help page (click Help at top right to get there). There's also a tiny gray "Contact" link at bottom right -- you can also get to Etsy Support from there. :-)
We have been tracking this issue, and there appear to be, perhaps, more than one cause; there might be an internal glitch we are looking at, but others find that clearing their cache will fix the problem, which means some are browser based.
Could each person having this issue post a few listing numbers as examples? I'll take a look at each one and try to sort it out. Thanks!
