When using Call Directory Extension on iOS14.x, Phone app's call history not display Name with short number. on iOS13.x, Phone app's call history always displayed name of Call Directory Extension even short phone number. But, on iOS14.x, Phone app's call history does not display name of Call Directory Extension of short phone number. The apps are the same, but the display results are clearly different. The display result of iOS13 is correct. The display result of the history screen of iOS14.x is strange. Short number of Call directory extension's name(like 203, 4601) is not displayed in call history screen. However, when receiving a call(Incoming call screen), the name of Call Directory Extension is displayed correctly on both OS. And new discovery related to this issue. I registered 661010 by CallDirectoryExtension. in Phone's dial pad input 661010 -> unknown input +661010 -> displayed name of 661010 input 010661010 -> displayed name of 661010 very strange behavior. Call directory extension data are 202, 203, 204, 302, 306, 4601, 4606, 661010 Input +202, +203, +204, +302, +306, +4601, +4606, +661010 to dial pad, Names are displayed. This is a bug.
