Fix legacy position population (#1069)

* Reworked legacy position population
- Changed data structure to a static list of pairs to avoid unnecessary deep copies
- Fixed oversight which caused iteration over the value and not the key of the previous QMap

* clang-format pass :rolling_eyes:

* disambiguate pair order further
