Well there is an issue with free Blocksy theme and free Blocksy Comp.
After you activate the theme (v1.8.47), you will get the install or activate Blocksy Comp banner message regardless of if you have activated Blocksy Comp v1.8.48.
Therefore, to avoid issues here, do not click on the activate button in the banner, simply dismiss this and you should not get any issues.
Note that this is an issue with the FREE theme and the Free Blocksy Comp plugin, it is not our issue to fix, it is down to Blocksy own devs to do that.
All you need to worry about is Blocksy Comp Premium which is running fine.
