Why is my stock total wrong after adding stock to negative value

[gbimp]

My company uses PrestaShop 1.6.1.18, and we use Advanced Stock Management. I had received multiple pre-orders for a product so our stock was at -13. When we added 100 products, the new count was 99. I don't understand what happened.  Any ideas? Please let me know if you require additional information for this question.

 

Cheers!

No, it was not a double.

What update? Do you mean updating the platform? We haven't updated since we are relying on third party modules that affect a different part of the system (adding PO numbers to orders and more).

Oh, since we have this version of PrestaShop, we can't update PHP versions but here is my current build:

Database Info:

• MySQL: 5.7.39
• Engine: InnoDB

PHP: 5.6.40

Server Info:

• Linux x86_64 (CentOS Linux release 7.9.2009 (Core))
• Apache

Let me know if you require more info.
