Hi sachin
I am not sure about the text keys but normally (I mean like components/endpoints/quilts) if you exported and edited in the local and submit it, it will not override. If you want to override you need to delete that component and upload it again(which will have your code) or you can clear the studio and perform development through SDK using clear commands. Please go through the SDK document for more details.
Hope this may :)
Give kudos if you find my posts helpful or mark as solution if it answers your query.
Thanks,
Srujana Satya
