I was having issue with the same thing. I reinstalled with auto-aim indicator unchecked and still had problems. When I unchecked Direction indicator by RN, and re-checked Auto-aim indicator the problem went away, so for me, the problem was the Direction Indicator by RN.
I have tried several times to get these to work, both original and green version. The sights that end up loading look nothing like the sights are supposed to look and lack the information of the mod. I tried loading the sights using a different mod-pack and they loaded fine. When I switched back to Aslain's the sights didn't load correctly. This has been since 9.13 was uploaded. All the other gun sight mods seem to work correctly.
