Export Wizard take forever to compile

After installing the SDK manager 3.2.2, the export wizard takes very long to compile.

It creates a temp directory with a manifest.xml which has a lot of double lines.

For every line 4 files are created, so for the above lines 224 files are created. 

Is this a known issue, because before the update, the export wizard only took less than a minute.
