Open COI.aln in the multiline mode.
Rewind the alignment down.

Current state: the paragraph starting at character 505 is duplicated.
Scroll to bottom.
The paragraphs have been updated.
Repeat steps 3—5 until the entire alignment is selected in the Overview.
Delete the last paragraph for the last time and scroll the mouse wheel down.
Current state: scrolling cannot stop at the end, the scrollbar appears at the beginning and loops.
