Issue
Before, .astype("str") was applied to the input array. This created an output array of fixed-length strings of the size of the longest string in the table. Converting numpy object arrays to string arrays should be, therefore, avoided.
This bug stems from #3722, which fixed #3671, but introduced this issue. :)
