ID 538017 - 3x3 contact sheet cuts dialogue with more than a single line

Customer reported version
flix_6.5.0
 
Customer reported platform
mac.12
 
Steps to reproduce
 
1)Create a sequence with 9 panels

2)Add a single line of dialogue to one panel, 2 lines of dialogue to the next panel and 3 lines of dialogue to the 3rd

3)Create a contact sheet using the 3x3 template
 
Expected behaviour
A contact sheet should be generated with all lines of dialogue showing
 
Actual behaviour
A contact sheet is generated but only the first line of dialogue is shown.
 
Workaround
Use the 3x2 template. It doesn't fit as many panels per page, but there is more space between the panels and it can fit more dialogue.
