Listing files and directories returns mixed case sensitivity on the results. Is there a way to force case sensitive results? - dropbox-api

Question

I've created a folder structure as below, with some images in the subfolders.
Test 1
Test 2.1
Test 2.1.1
Test 2.1.2
Test 2.2
When calling 'getMetadataWithChildren' I seem to be having mixed case results returned such as:
Array
(
[hash] => fd2934448f39ea3aa37faca9bbf72beb
[revision] => 14666
[rev] => 394a08b41a0c
[thumb_exists] =>
[bytes] => 0
[modified] => Thu, 10 Jul 2014 11:18:25 +0000
[path] => /Test 1/Test 2.1
[is_dir] => 1
[icon] => folder
[root] => dropbox
[contents] => Array
(
[0] => Array
(
[revision] => 14672
[rev] => 395008b41a0c
[thumb_exists] => 1
[bytes] => 879394
[modified] => Thu, 10 Jul 2014 11:18:25 +0000
[client_mtime] => Tue, 14 Jul 2009 05:32:31 +0000
[path] => /test 1/Test 2.1/Chrysanthemum.jpg
[is_dir] =>
[icon] => page_white_picture
[root] => dropbox
[mime_type] => image/jpeg
[size] => 858.8 KB
)
[1] => Array
(
[revision] => 14670
[rev] => 394e08b41a0c
[thumb_exists] =>
[bytes] => 0
[modified] => Thu, 10 Jul 2014 11:18:25 +0000
[path] => /test 1/Test 2.1/Test 2.1.1
[is_dir] => 1
[icon] => folder
[root] => dropbox
[size] => 0 bytes
)
[2] => Array
(
[revision] => 14671
[rev] => 394f08b41a0c
[thumb_exists] =>
[bytes] => 0
[modified] => Thu, 10 Jul 2014 11:18:25 +0000
[path] => /test 1/Test 2.1/Test 2.1.2
[is_dir] => 1
[icon] => folder
[root] => dropbox
[size] => 0 bytes
)
)
[size] => 0 bytes
)
Note that in the 'contents' array, the path is not the same as the path provided (and as named in my Dropbox). I need the results to be the correct case sensitivity for grouping them in my application so am I missing something simple or is this an issue with the Dropbox API and the results that are returned?
Many thanks in advance!
