LineItems incorrect at both Contribution Level and Financial Accounts Level

Please see attached:

Nov. 27 (4.7.13) -> a contribution form from my iATS testgrid with a priceset that has three price fields - correctly generated: line items at the contribution level - as well as at the financial accounts level

Dec. 18 (4.7.14) -> exact same contribution form: no more line items -> the items are lumped at both the contribution level as well as the financial accounts level.

I've reproduced this on demo drupal - this is not related to iATS Payments Extension - it's the iATS testgrid that led me to discover this issue.
