Can't split bills on shared tab

I get an empty screen seemingly indefinitely when trying to split a bill on a shared tab. I’ve tried both bulk adding bills and doing them one by one but the totals and the split button content doesn’t load.

Details to reproduce:

  1. Choose a payment to split
  2. Choose add to shared tab and pick tab
  3. Observe screen doesn’t load content
