Continually asks me to install To Top plugin

Hi, Everytime I log into WP Admin I get a notification to install To Top. I believe it is already installed and functional on the site. However, if I try to install it I get the following error message: Installing Plugin: To top Downloading installation package from https://downloads.wordpress.org/plugin/to-top.zip… Unpacking the package… Installing the plugin… Destination folder already exists. /home/ecparkin/thismustbetheplace.io/wp-content/plugins/to-top/ Plugin installation failed. TGMPA v2.6.1 ----- I can't dismiss the install notification because it appear everytime I log in. Ideas? Thanks.
