Stock automatically allocated to all quotations. HELP!

SUGGESTED

Hello.

We are having issues with Sage automatically allocating stock to every open quotation in the system. We noticed this happening few days ago and are unable to fix it. 

Basically every time one of the employees create a new quotation Sage would FULLY allocated stock to the quotation. I have unallocated all stock from open quotations yesterday just to find it fully allocated again this morning. This completely messed up our stock levels. I have a negative stock for most products and are unable to fix it. Can someone point me in the right direction please?   

Thanking you in advance.
