Weird data in Avg. Cost

[raylarose-legstate]

I'm following 15 stocks or so on this wonderful tool. But I have two which show the same weird value in the avg. cost field and not sure why.

For example, with AMZN:

Avg. Cost: 38;5;188m

In my yaml, it's defined as:

• symbol: "AMZN"
  quantity: 0.027829
  unit_cost: 3593.37

Has anyone else seen this? (it was a free fractional share, which is why the quantity is so weird).
