Human Factors; Procedure
I was Pilot Monitoring during departure on the HOLTZ9. We were cleared direct to PEVEE waypoint; Captain (CA) selected PEVEE and we confirmed the selection. I looked away as he activated the fix. For some reason the fix was deleted and the CA reentered PEVEE and then resumed the SID. We were slightly NW of the fix before making the correction.
As PIC; I was pilot flying the HOLTZ9 RNAV departure. SoCal cleared us direct PEVEE. After entering it in FMS and selecting abeam points; aircraft turned towards HOLTZ intersection; for some reason; PEVEE got deleted. When I realized it; I re-created PEVEE waypoint. By now PEVEE was just NW of me; so I made an immediate turn to it; went direct; and resumed SID.
After receiving a direct clearance to PEVEE while flying the LAX HOLTZ9 SID; a slight track deviation resulted as the waypoint was inadvertently deleted while intending to execute direct PEVEE.
