Data are data. If there has been some kind of procedural error and it's not feasible to re-run the experiment, it's entirely legit to restrict your data down to the valid subset, if there is some easy way to do so. If, due to some error, only 10% of your data are actually valid, and you can identify that 10% post hoc, there is no reason not to analyze that 10%. It might redeem the entire experiment.

Ideally, yes, you re-run the experiment and try ensure that 100% of your data are valid. This is not always feasible, nor should it be absolutely required.
