You should have imported two Lync versions, 32 and 64 bit. You need to merge each one with just the corresponding version discovered from Inventory.
If you select the imported one, right-click > Actions > Resolve Duplicate Software Resources. Click Browse for the top line (where the imported software is at the moment) and in the search box type the exact version number. This should give you two resources, the imported one and the inventory one.
You need the Inventory one on the top line and the imported one on the bottom; then merge them.
If you have more than two entries for the version, keep merging them.but make sure you don't mix 32 and 64 bit versions.
