one shop theme translation effect to other shop as well

[PrS]

Hello experts,
I need you help in urgent. I am facing an issue with prestashop multistore theme translation. When I translate a perticular text for store one that will save for store two also. And if translate that string for store two then that will effect store one again. 

So the conclusion which i got is if we use same string for multiple shops, then the most recent shop translation will save for other shops as well. 

Its very urgent, please help me. My prestashop version is 1.7.5.2

Thank you.
