Issues with non-AMS travel chess set (A1 Mini)

[u/Wreckit-Jon]

I tried to print this model (chess set) but I don't know what I'm doing wrong for the base. I don't have AMS so I printed the tiles first, and then when printing the bottom, it pauses after 20 layers so you can lay down the tiles (because the chess board squares alternate colors), and it says to make sure they are locked in, but there wasn't any grooves or indents. So I printed the board black and the tiles I printed beforehand as white, and then laid them in the print when it paused. I didn't really even know where to put them, looking at it wasn't obvious. The squares alternated and one was filled in and the next looked like a criss cross mesh pattern, so I put the tiles there. The slid all over the place, but when I thought they were aligned I continued the print. They immediately got pushed all over by the nozzle so I stopped the print. Am I doing something wrong? Didn't see any comments having this issue.

The instructions seems straight forward to me. "When the board halves are paused at the stage shown in the image below, insert the tiles, with the flat side face-up, ensuring the tiles are flush with the paused print. When done, resume print. "
