Thanks for raising this issue, but I could not reproduce this with a fresh project using Apostrophe 3.44.0 or the most current 3.59.0. Please try bringing the project up after removing the apos-build and data folders to see if the problem persists.

If the problem does persist please provide a sample project so we can verify it. Thanks Dainis!
