PDO Error: Conversion failed when converting the nvarchar value 'structure' to data type int.:

Just started getting a strange error while building out new menus. A little hard to reproduce but it seems to mostly happen if I try to move a new menu to the top of the list on the 'Power Edit' tab. It will save/create the new item but throw the following error and not save the new order. If I repeat the same reorder action in the 'List Links' tab it works.

We are on:
Drupal 7.72
MSSQL: 11.00.300
PHP 5.5.11
IIS 8.5
