changing photo dimension in Photoshop may cause problem in Lightroom

When I process my photos in Photoshop often I extend edges so instead 2:3 photo I have 4:5 photo, so I could upload it correctly into Instagram.

So the NEF file in Lightroom is in 2:3. I can click "Edit in Photoshop" and edit it without changing aspect, save it as tiff, so in the Lightroom it appears as 2:3. But then, I can come back to Photoshop and fix the aspect by extending the edges - changing dimension of the photo. After that Lightroom often is confused. It shows photo with incorrect aspect and when I click develop it shows old 2:3 version.

Is there a way to "update" the photo after it is changed in PS? The only solution I found is to manually remove it from Lightroom then sync my directory again (importing again), which is really time consuming.
