Transparent blue and the serial number doesn't match. Must have gotten switched at some time. Might be worth a call to Ren to see if he would make you a new sticker with the correct information.
If you want to get rid of the barrel jack you can drill out the input jack hole with normal wood drill bits. When you have the hole to the proper size you will need to use a plastic or metal jack plate and drill pilot holes for the jack plate mounting screws. I use the Puretone input jacks. Check out youtube videos to help with this.
