There's a workaround for that: go where your game data's folder is located (normally: internal storage\Android\Data) and locate the folder com.bandainamcoent.dblegends_ww and then rename it like put some numbers after the ww (like com.bandainamcoent.dblegends_ww333). After that, uninstall the mod version and install the Play Store version. After finishing the instalation, rename the folder back to normal and run your game! Thank me later!
