Sorry for my english. I hope you can understand without a big problem.
What I did:
I wrote some text in korean. I selected 1~3 sentences and moved in another line. (Drag - click & hold - move - release )
The moved sentences (or not moved sentences. I’m not sure) are changed like nearby sentence. Which means, some text are duplicated and some text are DISAPPEARED.
So, I tried undo function. But it didn’t work as expected. It seems like the texts are not stored properly. I did undo every line and than redo again. I could see, some sentence are appeared (sometimes they disappeared after even I never erased them) and some sentence are never come up.
Things that might be helpful to know (Agenda version, OS and model, etc): Agenda and OS both newest version. MacBook 2016.
Thank you for reading this. I hope you can fix it.
