Port field does not persist manually entered values

### **Environment** Transmission 5.18.0 macOS Ventura 13.7.4 (22H420) Native macOS GUI ### **Summary** The **port** field in _Tools → Application Options → Transmission_ **will not** save any manually typed port value. You can type into the field, but the value is completely ignored unless it was set using the spinner arrows. The text you enter appears to take, but it does not persist after closing the dialog. ### **Steps to Reproduce** Go to: Tools → Application Options → Transmission _*You can also access this menu by other means and it does the same thing, we are just using this way for consistency_ Click the **port** field. Type **any** valid port (_example: 51413_). Click **OK** to save. Reopen the same menu: Tools → Application Options → Transmission Observe that the port has not changed. **the manually typed value was discarded.** **### Expected Behavior** Manually typing a port number (e.g., 51413) **should** update the field and persist after closing the dialog. Both typing and spinner increments should produce identical results and save correctly. ### **Actual Behavior** Manually typed values never save, regardless of validity. Only values set using the increment/decrement (“^ / v”) spinner persist. This makes the port field effectively read-only unless edited via spinner (“^ / v”). **### Impact** Users cannot use custom ports unless they manually scroll to them using the spinner, driving them absolutely mad from inconvenience! Prevents easily configuring other common default ports (51413) and required ranges for **_many_** setups.
