Yang jago script autohotkey minta bantuannya gan, ane butuh bantuan

I have script with autohotkey. The script is working like this:
It will auto type a message every minute and the next minute it will delete the message automatically.

This script is work before. I don't know what happened, but now the script is not work properly.

Auto type message is still working, but the auto delete message is not working anymore. The problem is when the script running and hit the code (delete message) it's only erase 1 character in the end of paragraph. Example

If i set auto message is :
"how to save the world"

In the next minute, the script only erase "d" Word. So it will be
"How to save the worl"

Please someone can fix it for me? I really needed help.

Please running it on discord to proof my work.

Here is the script :

Saya sih tiap kali stuck pasti langsung nanya disana

 

Coba postingnya di tambahin akan ada reward gan.
Banyak orang pintar dan baik hati diluaran sana, tapi saat seperti sekarang ini untuk bantuan hal kecilpun setidaknya ada tawaran reward, walau si penolong tidak mengharapkan (diterima atau tidak itu urusan belakangan).
