Custom measure problem: graph is right, tooltip value is wrong

[EDIT: solved. I deleted the measure, restarted Power BI and made a new measure with the same formula, no problems this time]

Hi all, 

I am having a problem with a simple measure I created. I have a table with data regarding how many people visit each page of a site, and I created a simple conversion measure: % of all people who complete the entire funnel. In other words, # of visits on the last page / # of visits on the first page. Here is the measure: 

CalcConversion = (sum('High Level Funnel'[Submit]))/(sum('High Level Funnel'[Welcome_Continue]))

Submit = visits to last page

Welcome_Continue = visits to first page 

The data table is also broken down by week and by product (I'll call them product A and product B). I would like a visual that shows overall conversion for both products, but can be filtered by a slicer to show product A and B individually as well. There are different amounts of product A and B visits each week so I can't take a simple average of conversion. So I made this measure, and I also calculated overall conversion in excel and imported that data separately to double check my measure. 

The problem: my measure looks right when I graph it, but the tooltips shows that conversion = 1 for every data point! There are also some weird formatting issues, with the y axis disappearing and the graph area leaving extra space below the x axis that I can't seem to adjust. I threw the values into a visual table to double check, and sure enough it's also showing as conversion = 1 for everything there as well. What's going on? How can I get the real values to appear in the tooltips, and is there a way to fix the formatting? 

Screenshot below: my new measure is graphed on the left, with my manual calculation on the right. As you can see the trend looks identical - appears that my measure is working correctly. But the table below shows the values are all equal to 1. 

Thanks for any help!
