There are multiple issues with your configuration.

You can't use use_direct_from_level for tile sources. num_levels is not a valid option, only for grids (you should see a warning on the console). link_single_color_images doesn't do anything when using disable_storage.

num_levels must match you tile source. Does you source have 25 levels?
