CSV File not importing correctly

We are trying to import a CSV file into PowerBI with columns that contain financial figures (both positive and negative decimal numbers). However when we try to change this column to a Decimal or Fixed Decimal Number type we get errors saying it is unable to convert the negative values.

Have attached some screenshots of one line that you can see in the CSV file as a negative but in Power BI without changing anything it's formatted it with a gap.

Any ideas why it is doing this and how to get around this?

Thanks in advance
