delay when searching for movies

i recently have noticed a delay (maybe 5-7 seconds) before the dialog shows for searching sources when i click on a movie or tv show in a popular addon. i thought the issue was the addon itself, so i uninstalled/reinstalled it. but that didnt fix the problem. so i installed a fresh version of kodi 17.1 and just the addon with the default skin and the problem was gone. then i installed the titan skin, and the problem happened again. just to be sure, i changed back to the standard skin, and the problem was gone again. i have noticed this on 16.1 & 17.1 too. Android operating system. any help would be appreciated .
