Custom Fields repeated after upgrading from DP 7.1.4 to DT 6.5.6

Hi,
We had DP 7.1.4. WP 3.9.1

Then we installed DT 6.5.6 in another directory and used the transfer plugin. Everything transferred ok. Now making tests.

But, we noticed that the only 2 custom fields (tel and physical_address) we had in DP 7.1.4 were displayed in DT 6.5.6 as Membership Packages. As a result, we had in DT 6.5.6 two Membership Packages: one named telefono (in English telephone) and the other named direccion_fisica (in English physical_address).

Interestingly, those two custom fields were not displayed in the Custom Fields area. The custom fields area was empty.

We proceeded to remove those 2 membership packages since we don’t need membership packages and then created the two custom fields and assigned them to Listing Packages.

The issue is, that now we have tel twice as well as direccion_fisica twice also. When the user tries to add a listing the system displays 4 custom fields instead of two.

Please help us solve this issue.

Thanks!
