Currently entitled amount cents is zero sometimes

Hi, I’m using API v2 to get members’ data. To verify the users’ tier, I check currently_entitled_amount_cents value and it works most of the times, but in some cases, the value is 0 though the user is shown as a valid patron on Patreon website

currently_entitled_amount_cents => 0,
last_charge_date => 2022-06-02T15:12:53.000+00:00,
next_charge_date => 2022-07-01T07:00:00.000+00:00,
will_pay_amount_cents => 0

This user became a patron on 14 July, but the next charge date is 1 July, and both currently_entitled_amount_cents and will_pay_amount_cents fields are 0.
Any reason for this to happen?

Is your campaign charge up front?

It is turned on in settings, but my phone number is not verified

Can you DM me the details of this patron (the api return). Also your Patreon page link.
