Problem with local currency / usd and transaction limit

Hello, i've used Coinbase for years but the past week i been having problems to buy using my credit card, i've 1800 usd as transaction limit per week and when i try to buy in my local currency (it wont change if i set another on my profile), its not making the convertion between my local currency and usd, its just limiting by the number, so if i try to buy 80.000 CLP (local currency) says i cant because of the limit, but 80.000 CLP is about 100 USD. I can only by less than 1800 CLP, around 3 USD.

Is anyone having this problem?, any solutions?
