Structure block doesn't create structure file when powered by redstone

Hello, for a system I made, I need to regenerate a map with the help of structure block. But, before it, I need to save the map in differents structure blocks. There is the bug. When command blocks powered the structure blocks in save mode with redstone block, structure blocks don't create file for the structure. Consequently, when I leave the world or quit Minecraft for a while and then go back, structure blocks can't load the map because there is no file. I joigned a video to show you the bug.
