Because I keep different team logos in different folders. Therefore, each folder has a config.xml file. I changed the logo in FM23, so I put the FM23 config file directly into the respective team folders under the graphics directory in FM26. In the men's soccer team folder, the config settings were applied, and the team emblem was indeed changed in the game. However, in the women's soccer team folder, the config settings were not applied, and the team emblem in the game was still the original emblem that came with FM26.
