This issue seems to be similar to this resolved bug https://support.ellislab.com/bugs/detail/11246/ from a previous version.
I have a Text Input field that has a button to call up the File Manager which works as expected. If I upload an image and “use it” the File Manager will close as it should, but the field will be left blank. I get the same result with an image that was previously uploaded to the server, however if the file is a document type (tried .doc and .pdf) the File Manager closes and the field is populated with a link to the file.
