Certain route points moved to France when reopening in planner

Hello,
I'm slowly planning route for upcoming race (mandatory waypoints/sections).
I have all my waypoints marked in folder and using them as waypoints in planner.

When I reopen previously saved route in planner, these points/waypoins number flags are in France (suppose to be in Slovenia). Seems like they latitude is stuck to 0. When I later do the change to routing (adding/moving other waypoints), calculation timeouts as too big.
Noticed in on multiple routes. Happens only on these points from library used in planner.
Tested in Firefox and Chromium.

Example of the route:
