Thanks for sending through the bug report.
This seems to be a downstream problem caused by one of the projects failing to load. Try turning off the setting and examining the list of load errors. One of these projects doesn't seem to have normal platform/configuration settings, see
http://www.ncrunch.net/documentation/considerations-and-constraints_project-build-platform-and-configuration for more details on this.
I've implemented a fix for this that will be released in v2.24. To get this solution working immediately, I recommend fixing the project load failure.
As crazy as it looks, the 37/36 issue is actually by design. While NCrunch loads your projects, it also identifies any dependencies these projects may have on other projects outside the solution. NCrunch will then load these dependencies recursively, so it can actually load more projects than are listed in the solution.
