Power BI publisher for Excel, date tables generated

Didn't know what other forum to post this in. I'm trying out Power BI publisher for Excel (https://powerbi.microsoft.com/en-us/documentation/powerbi-publisher-for-excel/) and I'm getting strange results.

When I connect to a dataset or report, I get the relevant tables but also a large amount of extra tables called "LocalDateTable" along with an what I presume is an identifying code (for example "LocalDateTable_22af143-4a4a-356a-bbb4-43ab535b6aa"). It looks like it's creating a datetable for every datecolumn in the dataset. This would be fine if they were labled in a way that would make it clear which column they refer to. I tried slicing the data with the dates and they do work, it's just that there is no way of knowing what date is being used (for example, could be a sales date or the date an employee was hired).

blocked the codes since I don't know what they are.

Anyone know how to either make them (the tables) disappear or make them automatically name themselves according to the column they reference? I tried creating my own date tables and reuploading/reconnecting but they are still generated.
