Aircraft failed to capture NAV course Build 1.2.3

I was vectoring to the final approach course for the ILS on 26R at EDDM. I selected direct and CRS IN to the fix outside the final approach fix. The FMA showed HDG in green and NAV in blue. The ND showed a solid green line on the inbound course between the fix and the intercept point and a solid green line from my plane symbol to the intercept point with a green circle at the intercept point. I was approaching the final approach course 30 degrees off of the inbound course. When the plane reached the intercept point circle the inbound course line turned to a dashed line and the plane continued on the original heading. I selected a heading back to intercept the inbound course from the other side, and the lines went solid green again but again the plane did not intercept the nav course. I tried one more time without success, so I just used selected heading until I started to receive the LOC and then flew a normal ILS from there.
