Unit Cost different and not showing

Hi,

I’m experiencing an issue where i wrote the unit cost is 600 but the line total ends up as RM3,000 (Image A). I found out it made the product as RM5 for 1 unit. I didn’t change any settings nor i could find what was causing this.

Also when i create another product and entered the unit cost 300 but the line total is now RM0.

Please refer to the image below.

Update.

After Clearing my browser cache it has solved the issue weirdly.
