cannot select engines on left since update

since the recent update which i just updated to 14.75
i cannot select the engines on the left (when the engines are showing) & cannot right click on engines on left (i.e. to select just dofollow engines)
the engines on the left only show when you restart gsa ser, other wise there is just a blank space on the left where the engines should be, it says “where to submit 343” but below that just a blank space, this is just since the lest update
