Version 8.09 - Trackers diffuse masking - possible bug

[Debbie]

In version 8.0.9, I found that when I run a model from version 7.4.8 that had a good "custom diffuse" tracker selected, it is now not masked correctly (it is on the edge).  Even if I go in in version 8.0.9 and select one that masks properly, after running it, it is on an edge again.  See image below.  This appears to be a bug with the custom diffuse tracker masking in version 8.0.9.  Can this be fixed?  It is not practical to always use "all trackers" for large arrays.  The problem may occur specifically when the trackers are tilted on the terrain.

This problem results in erroneous production jumps close to 1%, because the diffuse shade is only half accounted for.

Thanks in advance for the help PVsyst.

Also, when I tried to switch it from "custom tracker" to "all trackers", it did not correctly save this change when running the model.  The report still shows "custom tracker" and the shade losses are still lower than the prior model because that custom tracker is on an edge of the mask.
