<ncpus>0</ncpus> is a debug setting, David has said before that it shouldn't be used to limit the number of CPU cores in use, we have the 'On multiprocessors, use at most x processors' and the 'On multiprocessors, use at most 100% of the processors' settings for that,

Another example in "multiplicity" of configuration parameters.

And they wonder why people are confused by BOINC. They think the more options the better and they ignore the fact that every time they provide an option they force the user to make a decision. When users are running software for charity they don't have motivation to spend time and effort making a lot of decisions unless the option is well documented and they don't have to look very far to find the documentation. They want it all done, installed and ready to go in 10 clicks or less. Anything more is an annoyance to them.

Responses to this line of reasoning will begin with "well if you don't like it go make your own BOINC". If we persist after that we will be banished so be careful what you say.

The error seems to be with <ncpus>0</ncpus>
I am getting GPU units just fine, but I'm still getting CPU units.

Use the project preferences to set "use CPU" to No and whichever GPU(s) you have to Yes.

The bug here is that you're still expecting BOINC 7.0 to work like previous BOINC versions did, where it will fetch work for whatever project e.g. when it's just uploaded & reported work for that project. Sort of to top off the cache all the time.

BOINC 7.0 does not work this way. It will only fetch work when the total work cache is below that of the minimum work buffer value and then it will only fetch work from the project with the highest priority (priority == 0, or close to it, like -0.05), and only if that project does not have work, will it fetch work from the next, and the next, etc.
