### Operating system and Environment details

AWS amazon linux stock

### Description of the Issue (and unexpected/desired result)
If a new KV is created with the /v1/txn api call, the key can be examined and recalled via the API, but the UI displays only one blank key.

Clicking the blank key causes the blank key to disappear, leaving the UI without an entry for the KV created via the API

### Reproduction steps

Install and configure consul 0.7.0 configured with UI.

Add a key and value using the /v1/txn curl command.

View the created KV using a curl command.

View the UI and see only a single blank box where the key value should be.


### Log Fragments or Link to [gist](https://gist.github.com/)

Include appropriate Client or Server log fragments. If the log is longer
than a few dozen lines, please include the URL to the
[gist](https://gist.github.com/).

TIP: Use `-log-level=TRACE` on the client and server to capture the maximum log detail.
