NER labeling includes unselected text

**Describe the bug**
A clear and concise description of what the bug is.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a project
2. Load text data
3. Go for NER labeling
4. Select text without a comma after it (see screenshot)
5. Selected text is labeled including the comma which was not selected

**Expected behavior**
When I label text under selection, I expect only the selected text to be labeled. In my case, the comma after the name was included in the label even though I did not select it.
