Remove extraneous items from a Babel box

Steps to Reproduce:

2. Remove unwanted parameters (with trashcan icon).
3. Apply changes.

Actual Results:
Three items were correctly removed, but two that were kept were not displayed in VisualEditor. (See screenshot to compare diff to VisualEditor's display.)

Expected Results:
The transcluded {{#babel:en}} function would display correctly.

Reproducible: Yes
