Can't complete installation of 7pace

This installation process has been a nightmare. I've run into several errors already which I had to work a while to resolve. Now after finally reaching the point where it begins adding the buttons to each work item, it then gets another error:

The element 'ALLOWEDVALUES' has incomplete content. List of possible elements expected: 'GLOBALLIST, LISTITEM'.
TF237070: Importing the definition failed. The definition you are trying to import did not validate against the schema. Edit the definition, then try to import it again.

I have gone through the configuration for every work item type and verified that each field contains only one entry of ALLOWEDVALUES and that within each instance of ALLOWEDVALUES, the only elements present are LISTITEMs.

However, I cannot seem to proceed past this point because of this strange error. Would be GREAT if your installation errors gave some more clues as to where exactly it's failing. How can I resolve this or get more details on where it encounters this issue (i.e. which work item type)?
