Helpcase titles deleting

[maxhdt]

Hello

I am trying to set titles in helpcase but after generate helpcase the titles always being erased

1. change title (ok)
2. generate (ok)
3. close helpcase (ok)
4. open helpcase (ok)
5. generate (all titles erased)

Practice:
Setting title

All ok

Then after close > open > generate the titles are being erased

Thanks
