Lost Attributes with Explode

I'm working on Electrical drawing and I use a lot of symbols (blocks with attributes) to create the circuits. On occasion I have to create a custom symbol for a particular device and with AutoCAD I simply picked a suitable existing symbol, inserted it in the drawing, exploded it, modified the entities from the exploded block, adding new entities and removing others as needed then used the "Block" command to create a new symbol.

If I try to do the same with Draftsight it turns all the Block attributes into normal text, WHY!!!!!!

If I explode a block I want to change it to its original entities not redefine them. Is there a fix or way around this?

Regards
