EDIT 02.04.2024 - Check my last comment - recommend using Webflow Localization instead of Weglot
Well Ali, glad I was able provide you the solution 18 months later 
If anyone is curious - you can develop English-Arabic websites using Webflow + Weglot. But you need a specific system for that.
I highly suggest anyone in touch with Arabic/Hebrew to use RTLflow, which is a system we created at Derokki for structured, scalable RTL Webflow Development at Enterprise Level:
Hope this helps!
