applescript garbled

I have several Applescripts that wrote recently that work perfectly but when I open them in Script Editor they look garbled.

Here is an example snippet:

--find the line that the thumbs tag is on

«event R*chFind» thumbsLine with «class SelM» given «class FnIn»:text 1 of «class TxtW» 1, «class Opts»:{«class SMod»:text, «class STop»:true, «class Rvrs»:false, «class Case»:false, «class Wrds»:false, «class ExSl»:false}

copy the «class SLin» of «class pusl» of window 1 to thumbsLineCount

This is what it's supposed to look like:

find thumbsLine searching in text 1 of text window 1 options {search mode:text, starting at top:true, backwards:false, case sensitive:false, match words:false, extend selection:false} with selecting match

copy the startLine of selection of window 1 to thumbsLineCount

Sometimes Script Editor will open them fine and sometimes they're all garbled. I'm on Yosemite with all the latest updates.

Does anyone know what's going on?

Thanks
