Project not saving

I recently encountered this. I had a functional parameter that I would enter the default for. When I would save and close out then reopened the project, the default was not saved. I have also thought this happened to a math function as well where I would enter in some commands and saved but when I reopened the project, the commands were not there anymore. The only way I could get it to save properly was to re-order the calculation order. Is this a known issue, I don't know why the calculation order has anything to do with the program's ability to save the project. Using IQAN design 5.03
