Text from a column isn't shown if the only values are numbers

**Describe the bug**
If I import a CSV file with only numbers in one of the columns, then I try to display that column on the labeling interface, it does not appear.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a new project and import this CSV file:

```
text,label
bob,1
susan,2
john,3
```

2. Use this code for the labeling interface:

```xml

</View>
```

3. Open a labeling task on any of the three items. It will show the `text` field but not the `label` field.

Note that if I then import another CSV file where I only change one of the rows to be `one` instead of `1`, then all three of the new rows show up on the labeling task, but the original three still only show the `text` field.

**Expected behavior**
I expect to see the number as well as the text field when viewing the labeling interface.
