Hello,
Thank you for report the issue and I am sorry about the experience!
This is a known issue on ARCHICAD 22. Layout with long double-byte characters that surpass 63 characters can't be completely shown in Sheet Index. This behavior has been improved on ARCHICAD 23, but unfortunately, due to technical reasons, it was not possible to be ported back to ARCHICAD 22.
I am very sorry for the inconvenience and trouble caused by the defect! There is no workaround for this issue, unfortunately. But I hope that you will consider upgrading to ARCHICAD 23 to be able to receive latest updates and fixes in the future! Thank you for your understanding!
I wish you a great day!
Best regards,
Minh
