Created Quotation for Leads should also be seen when lead was converted to Customer

Hi All,
We have updated our ERP to V7…
I have noticed that upon creation of Quotation for leads, that same quotation is not showing upon viewing the customer (after conversion from Lead to Customer)…

Like for example, i have Lead no.1111…
i have created a quotation for that lead QTN-00001 dated 15/07/2016
on 18/07/2016, this Lead ordered the items included in this QTN.
In that case, we converted the Lead to customer (example: Customer AAA)

When we open Customer AAA, there is no quotation showing.

The quotation should also be showing since the lead and customer is linked together.
Thank you…

Have you raised an issue on github for this?
