Identical Rockets Don't Fire At Same Rate

Note that the enclosed save file has a Vulcan rocket, a core surrounded by six identical rockets arranged as radial stages (created using sixfold symmetry).  On launch, one of the six radial stages burns through its fuel and oxidizer faster than the other five.

ETA: Running on Windows 10, Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz   2.60 GHz, NVIDIA GeForce RTX 2070 with Max-Q Design, no mods.  To replicate, launch Vulcan (full throttle, pointed straight up), and note fuel and oxidizer readings.  You can also watch as one stage empties and the rocket tips over from asymmetrical thrust.  I expected all radial stages to burn through fuel and oxidizer at the same rate.  I know of no workaround.
