I guess I did not explain clearly. The first time I send from LR to edit in Photoshop, the Photoshop edits show up in LR. On subsequent round trips from LR to PS and back, the PS edits are not showing up in the LR Develop module, but these edits do show up in the LR Library Module. If I restart LR, these edits will finally show up in the LR Develop Module.
