Customer Group Pricing

I am running version 2.31 and I cannot do an export due to having customer group pricing extension. As each product has about a dozen prices depending on wholesaler level. I am getting this error:

Unknown column 'cg.name' in 'field list' SQL=SELECT ps.*, cg.name FROM `xxxx_mijoshop_product_special` ps LEFT JOIN `xxxx_mijoshop_customer_group` cg ON cg.customer_group_id=ps.customer_group_id WHERE ps.product_id BETWEEN 37 AND 3812 ORDER BY ps.product_id, name, ps.priority

Any solutions for this already? or what route should I take to fix it?

Oh ya I also have product tabs extension that i could use that data also in an export..
