General journals for tax wont reconcile and disappear from my unmatched transactions list

I have done general journals at 30/6/21 for tax and they wont disappear out of the unmatched transactions list. What could be the reasons? They are OK in the Trial Balance. Any advice very gratefully received -

Hi Magenta,
You could do this as a single journal instead of two separate journals clearing to account 91000.
Alternatively, you should be able to select the checkbox next to both journals and match them (the match box will appear when one or more transactions that net each other off are selected.

I hope this helps,
