Technical Error shipping sections configure

[luca1711]

PS version: 1.6.1.15

Hello everyone,

I was starting to configure my store (this is not the first time I make a prestashop site) and when I opened the shipping section i put those example, i need one then i deleted one and i decided to modify the other, when saving the changes, returns this error https://prnt.sc/hdo16v and after I find several duplicate couriers, every time I attempt to save a change, I create a duplicate and can not be deleted by answering them this error https://prnt.sc/hdo6u4 the courier took the name of the site title (I do not know why) so it turns out to be too long and obviously if I try to modify it I get the error I described.

Do you know the nature of this error in the courier section? Probably the tables are corrupt, how do you recommend solving them?

I can not locate the affected folder to do a restore.

Thanks to anyone who participates in this topic, any response will be appreciated.
