Queries from Access missing in PowerBI

Hi All,

new BI user here.

I have a model which;

1) has a front-end excel model, where users can update data and assumptions

2) linked (live) into an access database, where a few queries are run to calculate final costs etc. 

3) queries are imported from access into PowerBI. 

Am noticing that quite a few of my queries in access are missing in BI.

I've done some preliminary searches, and they are not union queries ..

can't seem to figure out why it would be missing!

Any help you can offer would be much appreciated

Jon
