Double rendering of component

[xyzaidw]

I'm facing this weird issue where react snap successfully crawls all the pages and generates static HTMLs and its awesome! BUT when I deploy my build to the server and go to a route that has a static html it first displays the static HTML, thats not interactable and then loads the actual rehydrated component underneath that! so basically I have 2 set of the same htmls.. one is interactable and one is static..
side note: this doesnt happen when i serve the build folder locally

what can be the issue here?? TIA
