Diff-Amp Calculator has a problem with ADA4937?

Trying to run simulation on ADA4937 with Diff-Amp Calculator, and no matter what the input or gain is, it thinks the input is clipped. What's going on?

    It turns out the Diff-Amp Calculator limit of 1.2V minimum on Vocm is accurate:

    The issue is that with AC coupled 1 scheme, you are at the edge of the input CM voltage range of 0.3V to 1.2V…
