Null values display previously retrieved values

Previously reported:

Wappler Version : 3.8.3
Operating System : mac
Server Model: node

Expected behavior

When making multiple calls to a server connect and displaying those results, any and all data previously retrieved should be removed, and replaced only with current data results.

Actual behavior

Columns that have data on the first call, but are null on the second, display the data from the first call

How to reproduce

Create a server connect that will potentially return null values for some data:

First call:
Screen Shot 2021-03-16 at 8.53.52 AM

Second call (aisle and possibleUnits now null):
Screen Shot 2021-03-16 at 8.54.06 AM

Display these results in a table and notice that the values from aisle and possibleUnits are retained.

Note that using .default(’’) as provided in the previously reported bug does not work here.
