Generally, when a mod fails to change stuff after being applied through the mod screen, it means that the mod folder is incorrectly positioned. This can result from extracting a mod into a new folder if the mod already comes inside a folder, or if the game's path to the mods folder has been changed.
Please check that the info.txt file is located at position "../Roaming/Strive/mods/AricsExpansion/info.txt", if there are more or less steps in the path then it will not work.
Just in case, multiple mod support was bugged until version 0.5.25.
