Near the end of the movie Jensen says they need the space station in that reality because they don't have time to rebuild it there. Yet at the start they say that they are just testing generating energy that way in space before building it on Earth. So they never planned to generate the energy in space for Earth.

A hull breach would not cause an entire room filled with water to freeze instantly. Water exposed to the vacuum of space would boil due to the lack of pressure.

Once they flooded the remaining parts of the station with oxygen, several shots have been fired from a pistol, that makes sounds like a regular firearm, and fires projectiles that look like normal bullets - without causing fire in an oxygen-rich environment. yet an explosion is caused by a co2 pressurized canister hitting the metal wall.

In the opening scene, it is stated that "the world's energy resources will be fully exhausted in five years". As of 2018, around 25% of the world's energy comes from renewable sources that can't be exhausted.

In this film we see one character (Tam) speaking Chinese exclusively, including for critical information during an emergency. In a later scene where Tam and Schmidt speak in Chinese, Volkov cannot eavesdrop on them due to his inability to understand Chinese.

International space station crews typically speak English, with a Russian language requirement if they are flying Russian craft. It's extremely unlikely that crews would use English and Chinese in this fashion however. We are shown that at least one crew member cannot understand Chinese, so there is a high risk of miscommunication during critical operations.

When the monitor is supposed to show "H2O breach" (around 1h 00mins), it shows a zero instead of the letter "O". (The subscript "2" is correctly formatted, but that's not possible here.)

When Michael is driving with Molly after rescuing her, while he is texting you can see the speedometer and tachometer are both at zero although they are clearly driving at freeway speeds.

The windows in the living quarters are on the outer edge of the spinning disk which would mean the artificial gravity created by the spin would pull in this direction as well. In the film the gravity acts towards the floor of each room and not towards the outer windows.

Characters regularly refer to an urgent power crisis on Earth. For example, Hamilton talks about how she installed an illegal power cell so that her children would have lights at night. Yet everyone on Earth is shown to be using energy at current day levels: they drive cars, have cellphones, watch broadcast television and use the internet.
