Insert section of merge statement formatted incorrectly

All,

This relates to Beta 13.0.0.25 of Toad for Oracle.

On a merge statement, the insert section has all 6 column values formatted on a single line.
I had expected this list to be stacked into 6 separate lines.

Have I missed or mis-entered an option?
Or is this a formatting bug?

Here’s my list of formatting options:

296
5.315.0
5.322

<LF_ConsecLFLimit>1</LF_ConsecLFLimit>
