When I have this Logitech Excel add-in installed, the "Queries & Connections" pane that is made visible after importing some data from CSV files appears blank, with nothing visible at all. The elements are generally still there (I can right click them and remove, edit etc) but the visibility is gone. After uninstalling the add on using Apps & Features in the Windows Settings (control panel) the issue immediately is resolved after restarting Excel (where it still persisted after restarting Excel without uninstalling it) so it is definitely an issue with the Logi+ add-in. This has persisted over many months with the latest versions of both Logi+ and Excel installed. As can be seen in the first screenshot, the pane is completely blank but the queries can still be right clicked and acted upon (though sometimes the popups generated by doing so are similarly affected) and in the second screenshot all that has been done is to uninstall the Logitech addin.
