Access Databases - [lnet.ucanaccess.Complex.SingleValue]

I am not allowed to have Microsoft Access installed on my machine, so I have to get in another way using Knime. Unfortunately, I have come across a table where a lot of values are showing as “[lnet.ucanaccess.Complex.SingleValue;@xxxxxx]”

Can anyone suggest what may be happening here and how I may be able to fix it and reveal the true value?
