TOPEKA, Kan. (AP) — Kansas officials are reviewing a contract with an Irish software company hired to build custom legislative software that some lawmakers say has been problematic.

The Wichita Eagle reports  Kansas has paid Dublin-based Propylon $15.8 million since 2005 to build software and provide technical support for the Legislative Information Systems and Services.

Legislative leaders have held off renewing the contract until the firm addresses problems with the software. Senate President Susan Wagle has said glitches in the software often forced staff members to work late during the 2015 session and delayed votes.

Propylon CEO John Harrington says crews are putting plans in place to address the requests from state staff.

House Speaker Ray Merrick says he’s pleased with progress so far in the state’s discussions with Propylon about addressing issues.
