Hidden integers being attached to my data in Azure ML

I've been trying to solve an issue with a piece of time data for a while now. I cannot convert it to DateTime using the Edit Metadata module, or turn it into a numeric value, or bin it.

However, every time I enter it into a model to be trained, the time values return with these underscored integers attached to them as _1, _2, _3, etc. They come at the end of a normal value - for example 01/02/2021 08:33*_1*. I'm starting to believe that this is some kind of hidden text or attachment to the source dataset which is also the reason why I can't do anything else with that entire column.

Any suggestions appreciated
