<p dir="ltr">Hi,<br>
Qgis can handle both projected and geographic CRS at the same time. If it is a Custom CRS, it could means the projection was not recognized by a software along its production line and could indicate a problem if it contains errors... Or someone tried to recreate a missing CRS. </p>
<p dir="ltr">Try to go back in the metadata if you have it in order to find more info like the EPSG code. Perhaps it could help you identify the problem. Try comparing the .prj file from two file that are supposed to be in the same CRS. Maybe that could help. </p>

Still struggling.... I am attaching the info from the prj file and
the extent info from the metadata for each shapefile:<br />
<br />
I noticed that the PROJCS is labeled as "Custom"...could that be
confusing QGIS?<br />
<br />
Or is it because one is a projected CRS and one is a geographic CRS?<br />

And make sure OTF is on.

You have no choice of setting a project CRS if OTF is off.

Different sources or different layer CRS shouldn't matter.

Shapefiles without .prj file are still existing in the world.

There is an option mentioned previously so that you can set how
QGIS
<br />
handles layers that it can't tell what the CRS is.

<br />
Settings -> Options, CRS Tab, CRS foor new layers.

If you can point us at the files you're using - or excerpts from
them

- then we might be able to understand where the problem is
better.

<br />
Or tell us the extent of every layer, as reported by Rightclick
-> Properties, metadata tab.
<br />

check if your layers are in the right place unless you
understand the

gotchas in using that service.

</blockquote>
<br />
I don't agree with that.
<br />
If some layers come up on the wrong part of the Earth, it is a
good reference to see which layers are right and which are wrong.
<br />
<br />
Natural Earth shapefiles can be a reference as well.
