Auto structure member creation generates strange structure member for enumeration

Version and Platform (required):

• Binary Ninja Version: 3.6.4783-dev, 6fc13294
• OS: macos

• CPU Architecture: arm64

Bug Description:
When FnGetSystemDEPPolicy is defined like this: typedef DEP_SYSTEM_POLICY_TYPE (* FnGetSystemDEPPolicy)(); and given the example code below:

163d572e  dbg->__offset(0x2b0).d = 0
163d5734  __builtin_memset(&dbg->__offset(0x2b8).q, 0, 0x21)
163d575e  HMODULE hModule = GetModuleHandleA("kernel32.dll")
163d576e  
...
163d5787  FnGetSystemDEPPolicy GetSystemDEPPolicy = GetSystemDEPPolicy
163d5791  
163d5791  if (GetSystemDEPPolicy == 0) {
163d579d    GetSystemDEPPolicy = GetProcAddress(hModule, "GetSystemDEPPolicy")
163d57a3    GetSystemDEPPolicy = GetSystemDEPPolicy
163d57a3  }
163d57b1  
163d57b1  dbg->__offset(0x2b0).d = GetSystemDEPPolicy()

When I press S on line 163d572e BN creates a member at 0x2b0 for dbg structure like this:

    enum : uint32_t
    {
        DEPPolicyAlwaysOff = 0x0,
        DEPPolicyAlwaysOn = 0x1,
        DEPPolicyOptIn = 0x2,
        DEPPolicyOptOut = 0x3,
        DEPTotalPolicyCount = 0x4
    } field_2b0;

Which is looks like not appropriate. I expect BN to create a structure member there which have a DEP_SYSTEM_POLICY_TYPE type. When member created like that (enum _DEP_SYSTEM_POLICY_TYPE field_2b0) even if I'm able to change the type from linear view with Y, I'm not able to change it from types sidebar.

Steps To Reproduce:
I don't know how to reproduce this in another binary.

Expected Behavior:
I expect BN to create a member there with type DEP_SYSTEM_POLICY_TYPE.

Screenshots:

Start with the auto structure member creation triggered by S at 0x2b0 in the provided example, comparing the generated enum member with the expected DEP_SYSTEM_POLICY_TYPE. Investigate why the member cannot be changed from the Types sidebar; done when a reproducible case creates the member with the expected type and supports the intended type editing behavior.
