Describe the bug
Sometimes aggregate alerts aren't shown in the corresponding table under metrics.

To Reproduce
Steps to reproduce the behavior:

1. Set up aggregate alerts as shown in the local deployment tutorial
2. Go to http://localhost:49080/dashboard
3. Click on the Flow for which alert was created
4. Scroll down to corresponding table for the aggregate alert
5. Observe no data shown in table

Expected behavior
Alert fires and time & description shown in table

Version of Data Accelerator
v.1.1

Desktop (please complete the following information):

• macOS Mojave 10.14.4
• Google Chrome Version 76.0.3809.132 (Official Build) (64-bit)

Additional context
I also tried:

• Stopping & redeploying Data Accelerator
• Restarting the job
• Turning off alerts for all other rules & restarting job
  Along the way, Events Ingested Today & Avg Events/Min were no longer loading. The job went idle at a couple times without me stopping it.
