QIF import fails for zero sum split

[B Wooster]

I read some archived postings on this issue regarding Moneydance vs Quicken
imports, but that was a 2008 posting, and it seems to suggest that Quicken
should be fine.

I'm totally new to GnuCash, just trying it out. Have over 20 years of
Quicken 2006 data, the QIF file is around 2.3M.

Imported it all as a single QIF file, and all import info screens seemed to
do the right thing (except it could not import many of the investment
actions such as grant, exercise, etc).

But the first key problem is that $0 Split Transactions in my checking
account were wrongly imported.
Non-$0 splits seem to be have been handled fine.
For each of the $0 splits, every transfer listed in the split was converted
to a
Withdrawal column item in my GnuCash Checking account.
One easy way for me to spot these was the "n" in the R column of the
checking account! All other lines have a "y" in there (reconciled), at
least for this Quicken 2006 account.

Is this a known issue, and is there any workaround for a fix?
