Flip: Cache data (cache mode loss on scene reopen)

Playing around with flip fluid simulation and I found one thing - the cached data is playing in viewport, but fluid properties does not see that the data is already cached (there is ‘cache data’ button only, but ‘free data’ button should be there instead), so I can’t start to do some tests with meshing, because of data cache mode… It is painful with hard and long simulations, because it means that I have to resim all the data again.
Is there any way to make flip properties work properly - to be not in a ‘write’ mode (cache data) if data is already cached?
