Aside from the obvious point that the OP has not yet posted an example, we seem to be headed into another discussion about an issue that everyone talks about but I am not sure everyone understands.
I now see the dreaded focusing charts being mentioned, and , I'm sure, another round of discussion about the results.
FOcusing charts are the biggest problem with the front focusing issue, because so few people use them correctly.
In order to make sure we don't go back down the wrong path, please note the following.
The charts are to be used at a 45 degree angle, and the camera is to be set level with the center of the chart, and the axis of the lens at right angles to the chart centerline. This is best achieved if the camera is mounted level on a tripod, and the chart is moved away from the camera, and set at an angle.
Also please note that depth of field is NOT linear. In fact, if focused correctly on the centerline, the range of acceptable focus on the chart is 1/3 in front of the line, 2/3 behind the line. This causes many to believe the lens back focuses when it does not.
Please also note that the exact location of the focusing sensor can have a large impact on these results, as does slight vertical misalligmnebt of the target on the sensor, That is why hand held shots can be so far off. You need to be very careful, and I would suggest trying the shot at all 4 camera positions including upside down (or slanting the focusing target the opposite way), focusing always on the same spot.
Then let's see the results
By the way, have I mentioned the OP has not yet posted examples
