Hello,
1) Do you use the latest version of Core plugin? https://www.8theme.com/documentation/xstore/plugins/plugins-update/
Please try to disable “Enable sticky sidebar” in Theme Options > Shop > Shop page Layout. Then clear cache and check.
2) Please make sure that Shop page is selected in WooCoomerce > Settings > Products > http://prntscr.com/m2kmms
