LINDA 737NGX Profile with MPanel

Hi.Whilst I appreciate the LINDA 737NGX profile is configured for MCP 1 & 2 and not the MPanel I am trying to get the best out of it as possible, largely with great success.I find with the MPanel that when I am flying the NGX under LNAV and VNAV, I can no longer use the MPanel to set the Altitude, it keeps jumping to the heading setting or speed setting.Is this in anyway caused by the lua script or is there a way I could prevent that from happening?If so the 737NGX profile would work perfectly with the MPanel.Thanks for any support you can provide.Chris
