unable to edit or remove hyperlink from organisation chart
 

I have an organisation chart on a worksheet. The chart is too big
for one worksheet so I used hyperlinks to other worksheets in the workbook
where the chart 'continues'.

I re-named the destination worksheet and the hyperlink stopped working.

However when I right click organisation chart items that contain the
hyperlinks I do not get the option to remove or edit the hyperlink -since I
cannot edit or remove the hyperlinks the workbook is now useless.
Any suggestions or help is much appreciated
