After reloading Normal Map it looks totally different

[Jinn500]

Hi,

I baked all the maps and started working. I noticed some weird glitches in my normal map, so I adjusted it in photoshop (hence you cannot fix paint normalmaps in substance) I reload it again in the shelf, and I also updated it in the layer stack. and now the normal map looks weird and shows very hard lines.

I must say I exported the normal map on openGL because I read somewhere that it was better for rendering later in blender. I found this on the substance site:
https://docs.substance3d.com/spdoc/normal-map-looks-incorrect-when-loaded-in-layer-or-tool-properties-144998405.html
to change it back to DirectX. But that button is not there is 7.1

Is that the sollution?
what should I do?
