DNS TXT Record breaks after 127 characters

Has anyone experienced the same issue? We are trying to create SPF record as TXT record under the Peplink DNS settings, which is necessary for Email operations. We noticed that the pasted SPF text breaks after 127 characters then continues. So we want to achieve “Full-SPF-Text”, but what we get is “PART-1 of SPF Text equal to 127” “PART-2 of SPF Text”, in two separate double-quotes pairs, where Full-SPF-Text= PART-1 & PART-2 concatenated.
Is this normal? Kindly advise!
We are using LB-710 with latest 7.1.1 release.
