Size difference between an empty old map (~4.9) and an empty new map (4.16-4.18))

Hello developers,

Today I encountered a problem testing some new features in my project.
Time ago I created a test map with the 4.9 version of the engine. Cleaning this map and deleting everything the dimension of that map is 41 kb. The map is completly empty!
If I create a new map now with the 4.16 version of the engine the size is around 17kb.
I already used this command to clear the old map settings “-run=resavepackages” with no results.

Anyone has an explanation?

Thanks in advance!
