Last time I bought an OEM oil drain bolt washer it was made of solid aluminum.
Same goes for the transmission and diff washers.
Aluminum has the property to harden under load/stress.
So when you tighten the drain bolt the washer hardens a bit and might not seal (but most times it does ) the second time you tighten the drain bolt.
What you could do, is clean the washer and gently and evenly heat it up to about 300C (570F) and keep it at that temp for a minute or so and let it cool down on its own to soften it up to its original state.
The heat of the engine is not enough to soften it.
Keep a new one at hand, because if you heat it up to much or to fast it will melt
