Hi,
The value in "price_access" is indeed wrong. Instead of 15|15|15|16|16|16|17|17|17 it should be:
,15,|,15,|,15,|,16,|,16,|,16,|,17,|,17,|,17,
Trailing commas are necessary because of the way the MySQL queries are done on the frontend.
In the backend, it displays fine because the system is nice enough to try to understand it, but on the frontend, that's not possible due to the way the MySQL queries are optimized.
If you export a CSV of a product properly configured via the interface, you'll also see the commas for the price_access column.
