Rendered exceptions are going crazy

I have a simple design where I have a PlotView in XAML bound to a PlotModel that is a property of a view-model object.

Within the view-model object, I have code that updates the PlotModel often (because I am plotting real-time data). For some reason, OxyPlot is throwing tons of exceptions at me, and they are all getting rendered to the PlotView, which is quite annoying.

Here is a video of the issue:

As you can see, I am using an AreaSeries. If you'd like to see code, I can post code. Although it is complaining about axes being defined, I have clearly defined the axes.

Any idea what is gong on? Any idea how I can suppress these exceptions from being rendered? They are quite annoying.
