A form I have access too; 'short_uuid': 'bada2955', currently only has 6 questions; however the positions under the API GET call report as follows:

{data: {relationships: {questions: {data: [
0['position'] = 1,
1['position'] = 3,
2['position'] = 5,
3['position'] = 6,
4['position'] = 7,
5['position'] = 16
]}
