Need help: save not working

I’m sure I’ve done some mistake here but can’t figure out what. Been trying to learn the save system in UE and worked well to save the player position and load it so I started making a system for multiple save slots.

The text box on the far left contains the name I chose for the save slot (which was “test pls work”), the first print shows that this works well and is saved in the “SaveSlot” string variable.
I then load a save which is only used in the main menu, containing info on what actual save slots are available.
After setting the array element I check what’s in it and it says there’s nothing there. :confused:

Super stuck, pls help! <3 (image is pretty high-res, you can zoom in to better see)

Am I correct in assuming:

  1. The save game exists?

  2. Index is sequential? ( or zero )

It’s not a bad idea to tick the ‘size to fit’ box.
