I am using Premier 2017, Ver R3, but had this problem thru several version of Quicken (I have been using Quicken since Quicken 99). Support has never been able to come up with a solution.
The full portfolio view omits several securities which are shown accurately in the individual account holdings view. Latest suggestion from Quicken Support was to use Portfolio X-ray which is a Morningstar provided investment analysis program and unrelated to the problem. There is no discernable difference in the way the securities data were entered and the data for those securities which appear correctly in both views.
Any ideas? Other than get a new investment management program.
