Not all product attribute titles coming up on the order confirmation email

[celshader]

When the order confirmation email comes through it shows what the user has purchased as it should with all the attributes of the product.

The last attribute on the list however is missing a title.

 

1 x Shutter () = $2,333.10

Outer Height (mm): 1300

Outer Width (mm): 1700

Number of Panels: 2

Shutter Style: Bi-fold

Shutter Finish: Lacquered

Total Square Area (m²): 2.21

Bifold - Style Option: H6 - Without Bottom Track

2333.10

 

The last line of the order should read.

 

Individual Price (AUD$): 2333.10

 

but the title is missing

 

It comes up properly in the shopping cart and the order history, just not the email

 

Thanks in advance for any help.
