Based on my understanding, the issue appears to be related to the use of the octal number system. Specifically, any numbers with any digit greater than seven are being parsed incorrectly.

The octal number system is a base-8 numeral system that uses eight digits (0-7). When a number is written with a leading zero, it is interpreted as an octal number. However, if the number contains any digit greater than seven, it exceeds the maximum value that can be represented in the octal system and may result in parsing errors.

Therefore, in your case, it is likely that the numbers with digits greater than seven are being interpreted as octal numbers and causing the parsing issues. To address this problem, you may need to consider using a different numbering system or modifying the way the numbers are represented to avoid the limitations of the octal system.

I have found the same issue with values such as '080', '090', '0008', etc.
