HTML report: %KO - NaN vs 0.00

[rado-o]

I bumped Gatling Java dependency to version 3.13.4 (previously used version: 3.12.0).
All executed requests were successful. However, the KO percentage is not consistent in the HTML report: for the most requests a double value (0.00) is logged for %KO. For some requests "NaN" is logged. Please see the attached screenshot for the reference.
My assumption: In the previous version there is no comma present for a higher count of requests, example: 49224. In the current version there is a comma present, example 49,224. I think the value cannot be parsed properly when counting percentage.

Current version 3.13.4:

Version 3.12.0:

Gatling version: 3.13.4
Java version: 21.0.5
Kotlin version: 2.1.10
