Line Style Scales from different drawings off by factor of 12

Question

Microstation user for 12+ years, have never been able to figure out line style scales. I get files from different surveyors that I have to standardize. Some files I just can't get the line style scales to work right, even though every toggle and setting seems the same. In these files, I reference in a standard file that looks correct. However, when I copy lines or inherit properties from lines in the sample, they are too small by a factor of 12. Here are all the settings I have gone through to make sure the files are the same: 
 
 View attributes > Line Styles turned on 
 Drawing scale = Full size 1=1 
 Settings > Design File > Global line style scale = 1 
 Scale of individual lines = Drawing Scale 
 Element > Line Styles > Custom > Scale Factor = drawing scale 
 Level overrides off 
 Model > Properties >
 
 Annotation scale off 
 Propagate annotation scale off 
 LTscale = Global line style scale = 1

Reference settings
 
 Annotation scale off 
 Global linestyle scale = Master 
 True scale on 
 Scale line styles by reference scale off

Right click level > level properties > Styles > nothing toggled 
 
 There still seems to be some setting that is causing the lines to be off by a factor of 12.

 That leads me to another possible issue. The line styles may have been copied into the file so the library is being ignored. I am looking at this in Microstation SS10, but it can be an issue in any version. Go to <Element <Line styles <Custom and you will see a dialog with the line styles. Highlight a line style and you can see where the definition is coming from. The telephone line style is in the Cicero file rather than the library. When a resource is used from a library the definition is copied into the active file. It should retain a link to the library, but if you received this file from another firm the link is probably broken or they copied the line styles into the file so you would be able to see the styles rather than solid lines. Try to select all the elements using the telephone line style and switch them to a different line style like zero. The n go to your key-in browser and type in "delete unused linestyles" (no quotes). Then select those element again and apply the line style from the library. That should solve the issue.

So in the incorrect file I used the Element Information dialog on the Telephone line style and switched the value to 144.0000 which scale the line style up (12x) to match the Laramie file 
 This is the method I tried to describe earlier. It has nothing to do with how the line styles are created.

I did confirm that the line style definitions are part of the .dgn file. Switch the elements to another line style and using delete unused linestyles removes the internal definition and reapplying the line style works with the library.

I would agree with "mwlong" I believe the two different files received there common linestyle named lines from different resources. 
 I would also agree that since the graphics look the same and it is mainly a scale issue, the that two were created based on different resolutions.
