JObject.Parse throws error on valid Json - json.net

Question

Searching on 'Newtonsoft.Json.JsonReaderException: Additional text encountered after finished reading JSON content: {. Path '', ...' finds at least 3 SO questions all of which were traced to invalid Json.
I've tried 3 different validators on:
[{"Imported": "This registration imported on: 06/20/2016"},{"ContactInfoUpdated": " Street Address2: Suite 222 to Shipping Address2: "}]
and all three report it as valid. And yet the runtime error tosses that same 'Additional text encountered...':
if (!string.IsNullOrWhiteSpace(UserComments))
{
JToken addresses;
addresses = JObject.Parse(UserComments).GetValue("CarbonCopy"); //errors here
if (!ReferenceEquals(null, addresses))
{
//stuff
}
}
To establish that there are no unintended characters after the json closes, here's the sql:
UPDATE dbo.[Order] SET UserComments = '[{"Imported": "This registration imported on: 06/20/2016"},{"ContactInfoUpdated": " Street Address2: Suite 222 to Shipping Address2: "}]' WHERE idOrder =121050

With thanks to Brian's prompting I found this post to be very helpful:
Get Value from JSON using JArray
My json is somewhat unusual in that it's an array of dissimilar objects. Instead of a series of name/value pair where Name stays constant, my 'UserComments' field contains pairs where Name can be 'ProfileWasEdited', 'CCRequested', 'Feedback', and so on.
In order to accommodate that type of structure I need to test against the Name property:
var fields = JToken.Parse(UserComments);
var isCC = "";
foreach (JObject content in fields.Children<JObject>())
{
foreach (JProperty prop in content.Properties())
{
if (prop.Name == "CarbonCopy")
isCC = prop.Value.ToString();
}
}
Resharper informs me that I can Linq-ize the above to:
foreach (JProperty prop in fields.Children<JObject>().SelectMany(content => content.Properties().Where(prop => prop.Name == "CarbonCopy")))
{
isCC = prop.Value.ToString();
}
