Why are some segments locked?

Why do segments appear locked and why I cannot modify them?

When opening your Matecat translation editor you could notice that some segments appear as already approved and locked.

This happens when Matecat detects an in-context exact match from the TM.

An ICE match is determined when a segment has a 100% match from the TM associated with the project and has the same context as well (it is preceded and followed by the same segment).

This prevents you from translating again the same segment you or someone else has already translated.

However, if you need to edit the segment anyway, you can just unlock the segment, by clicking on the locker icon on the left.

Remember that in this case, you will need to click on Translate to save your translation.
