I won't declare "NTFS Read Only" as normal, in any device or OS. (But correct me if i'm wrong...)
This must be a Bug somekind...
Confirmed, this is not normal. It is neither normal for Q10 Pro. Use myself Samba Server on Q10 pro which let me access all media sources in read/write mode formatted with NTFS. If the problem is limited to one stick type/brand I would live with the workaround. exFAT is in fact an excellent file system for USB-sticks and SD-CARDS. The portability between multiple platforms is becoming even better for exFAT than for NTFS (=The new defacto standard above 32 GByte).
If it is a generic problem the first thing to do is a full re-install using the pin procedure. For testing/reporting one should use standard file-browser facilities included with the box being Media Center in this case (new, rename, delete are all write operations).
The provided NTFS drivers with Android are known not to be flexible and support only commonly used settings/variables. So some specific characteristics of a brand/type may lead to problems. Have seen this before on multiple Android based platforms for both flash and HDD drives.
For the same reason be sure to use only standard Windows for formatting to NTFS and no other tools or OS.
