Looks okay so far ...

No, you're wrong --- that output is perfectly correct. The
multidimarray value contains a comma, and therefore it needs to be
double-quoted according to the rules for composite type I/O. The 1-dim
array value would have gotten quoted, too, had it contained more than
one element.

It sounds like you are using some code that mistakenly thinks that
double quotes have a semantic meaning here. They do not. They are just
there to delimit members of the row value, not to tell you what type the
members are.
