The Googlebot doesn't add query string to the end of pages it indexes. There is one of two options here, either the Google SERP has a glitch on a few web servers which is adding that query string to the end of the URL (unlikely) or two two the links on your page are being either rendered in a malformed way by Code Igniter or being altered at run time by javascript which is mangling the link without you realising it. Ever since Google became capable of assessing how javascript changes page content and tracking javascript-based page changes for indexing purposes javascript based changes to pages has become even more important and a link that gets changed by javascript can still cause the exact same type of query string issues that used to be restricted to server side rendering issues.
