Error 1026 in "Lv Proj Document Type.lvlib:Project Parser.lvlib:Get Dqmh Module Info.vi"

This issue crops up when trying to generate documentation using Antidoc v2.0.4.124 in LabVIEW 2020 64 bit on a project with 36 singleton modules and 12 cloneable modules. Looks like antidoc has issues closing some VI references as they are invalid.

See below error string:

Error At Exit:
Error 1026 occurred at Close Reference in Lv Proj Document Type.lvlib:Project Parser.lvlib:Get Dqmh Module Info.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Dqmh Module.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Parse Library References for Documentable Types.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Project.vi->Lv Proj Document Type.lvlib:Lv Proj.lvclass:Parse.vi->antidoc.vi

Possible reason(s):

LabVIEW: (Hex 0x402) VI Reference is invalid.

Debugging: Lv Proj Document Type.lvlib:Project Parser.lvlib:Get Dqmh Module Info.vi has two instances of Close Reference.vi, I tried removing each individually. The issue seems to be occurring only in the top instance - see image below.

After removing both instances of Close Reference.vi I get a the following error:

Error At Exit:
Error 43 occurred at Property Node (arg 1) in Lv Proj Document Type.lvlib:Project Parser.lvlib:Get Dqmh Module Info.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Dqmh Module.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Parse Library References for Documentable Types.vi->Lv Proj Document Type.lvlib:Project Parser.lvlib:Project.vi->Lv Proj Document Type.lvlib:Lv Proj.lvclass:Parse.vi->antidoc.vi

Possible reason(s):

LabVIEW: (Hex 0x2B) Operation cancelled by user.

This error doesn't seem to cause any issue with output - documentation is generated as normal.
