Tile + Interactive Tool Not Working

[qlql]

Hi! I've been trying to make histograms with custom bins (decided to use the interactive chart one since that worked, while the histogram didn't). I used the tile tool to make tiles (bins) and graphed the following: 

When I double check it with my original dataset, one of the histograms is showing the right values, but the rest are off in the counts. Does anyone know what the issue might be? 

As a secondary question, is there a way to label the Tile_Num as custom titles? I tried using the Formula tool to assign text names to the bins, but it didn't graph because they weren't numeric values. 

Thank you!
