Bug: event with two dates displays wrong in org-agenda

[rameiko87]

I have the following entry in one of my org files:

** party <2023-12-02 Sat>. Meet Jack <2023-12-02 Sat 16:15>

This appears in my org agenda twice, both times at 16:15. I would expect 
it should appear once at 16:15 and once as a general event for the day!
