[2.0.76] Mismatching amount of fluid (water) in Heat Exchanger after Cloning

[WhiteDragon]

I am using Clone tool from Editor Extensions to replicate bug.
Heat Exchanger and single pipe, for easy amount of Water observation.
First HE have 147 Water.
Clone, and second HE have 294, it is strange, because pipe only have 31.2 and HE have limit of 200.

I do not think that bug can happen during ordinary gameplay, even with mods or SA, but in Space Exploration Clone function is used to "move" spaceships between surfaces.
