V4.1.x Make an Offer module based on Rating Module

[business +]

I am building a Make an Offer module based on the rating module available with 68C.
I have copied the files in /rating to /offer. In the files I have made all references for "rating" to "offer" and all file paths have been updated. The tables are also duplicated to rating_offer and rating_settings_offer. In the files under /offer all references to tables have been updated to point to the new tables. I am able to submit offers and the correct tables are updated. But when showing the existing offers on viewlisting.tpl (in the case of listing ratings, these the are the ratings), it seems to be taking the data from the original tables. But if I rename the /rating folder to, say /rating1, it shows the data from the offer tables. It appears that if the /rating folder is there, the rating tables are used. If /rating folder is renamed/removed, correct tables are used in the offer module. The files under /offer all use the offer tables.

How can I have the /rating and /offer module at the same time and still have the "offer" module working with its own tables? Thanks.

I am using v4.2 and default template.
