Ctrl Left Click Wrong Location

We've just upgraded to Resharper Ultimate (2017.2.2) and VS2017 from VS2008 and Resharper 7.1.3 and I'm having some issues...

There seems to be a strange issue with Ctrl + Left Click (Go to declaration). Sometimes it will bring me right to where I expect it to (at the top of the method). Sometimes it seems to be 10 or 20 lines away.

And sometimes (rarely, and apparently randomly) it will navigate me to a completely different method in a decompiled class in some other library that I never clicked on. That is really really annoying. Here's an example I just tested:

My class has this method:

public void Stop()
{
Stop(new Tuple<ProgressForm, ManualResetEvent>(_dialog, null));
}

Somewhere else in my class I make a call to this Stop() method. I did ctrl + left mouse click and the following happened:

1. Brought me to the Stop() method.

2. Put cursor on the ManualResetEvent type.

3. Decompiled ManualResetEvent and in that decompiled class, the cursor is on the class name.

Obviously it should have just brought me to the Stop() method and put the cursor there. 

I have cleared Resharper cache, but I don't know what else to do. VS2017 never had the old version of Resharper installed. Could there have been something the older Resharper stored in my solution file that I need to delete?
