Hey,
I am using ZWCAD 2024 currently and I've created a dynamic block to be used in ZWCAD as an alternative to Multi-leaders to be an easier method to be able to DATAEXTRACT because my ZWCAD does not allow data extraction of MTEXT and MLEADERS unlike AutoCAD. I'd made the Dynamic Block to work exactly like a multileader would using, along with other parameters, Multiple Lookup Tables for rotating, extending and flipping the leader without affecting the order of text. That means they had to be created in licensed AutoCAD because ZWCAD's counterpart do not have the LookUp parameter yet. The blocks worked normally as intended for a while on regular usage(working on, closing and reopening the file multiple times), but they stopped behaving like a dynamic block altogether suddenly after a few days on reopening the file. The blocks now seem to have been assigned different names by the software (*U15, *U16, and so) from its original name(m-Drawing M-Leader Block).
 

I have noticed this behavior with some other dynamic blocks in the files that I receive from consultants once in a while and also in a fairly simple block with just a stretch parameter I'd made within ZWCAD. I'd tried to replace the corrupted blocks with the original dynamic block reference, which would have itself been sort of a tedious task as there were so many instances in the drawing, but ZWCAD no longer recognizes the corrupted blocks as "blocks".

ChatGPT and other LLMs are of limited help, so please help a brother understand and, if possible maybe, correct or avoid this issue. Or is there an alternative to this?
