The IL formset has some issues with updating, you'll need to uninstall and and reinstall it for the forms to be updated.

For Win10
Right click the Start button > Settings > Apps   scroll down the list to Proseries 2018, click Uninstall    It will act like its going to uninstall the whole program, dont panic, it wont!   Another window opens with a list of modules to uninstall, choose IL state.  

I believe for Win7, its under Control Panel > Add/Remove Programs  Uninstall PS18
