Version 2.0.7 of CSV Import has a responsive issue with the ‘Status’ tab- the table listing you import history adapts to the width of the file name, which is good, but when it does so it moves the Action column off screen so you can’t use the Undo feature.
Hmm, I’ll try to figure out what makes it decide to move a column over like that.
In any case, you should be able to scroll the table over to the right to still access that last column. Depending on your OS or browser, the scrollbar may not be obvious; clicking and dragging over to the right within the table, or pressing the right arrow on the keyboard should work also.
