Hello,
Thank you for reaching out to us.
Regarding your inquiry, it seems that the quantity selection on the front end is displaying predefined values (1-5), whereas you would like customers to have the flexibility to choose any quantity. To resolve this, please go to Single Product Builder with Elementor > edit template > change quantity style – https://prnt.sc/ov_o-QmMhPhR
