InCopyCC18 errors out if file is open in InDesignCC18

Editors using Incopy CC 18 get an error if they try to open am .indd file that designers have open in InDesign CC18. The whole point of InCopy for us is so that editors can work on files that designers are using. It only happens on files with .idlk files indicating it is open in InDesign. This did not happen before our upgrade to CC18.

Also when designers export multiple stories on one page to Incopy it automatically exports everyting with the file name as the first line, but then asks if we want to replace the .icml file it just auto-saved.
