I have also found problems with **Custom Attributes**. I always add custom parameter '**Description**' to all my components. Today I started modifying a project that I created a few months ago and when I try to add my custom parameter to the new components, it do not appear in the BOM.             I remember that before we had a CheckBox 'In BOM', that now disappeared.  Can you verify please? Thanks in advance. <br> <br>

I found a workaround in order to add the parameter '**Description**' and see it in the BOM. You have to select the component to which you want to add the parameter 'Description' and a component that already has that parameter. You will see something like this:  Since I had already tried adding the 'Description' parameter, I see two of them. You have to delete the one you can read. And in the one you cannot read, you write anything:  Then you can select the components separately and change the value of the custom parameter.    Now the BOM is OK: 

errata: **You have to delete the one you can read** -> **You have to delete the one you can't see in the BOM**

@jogagua How to fix it? They are doubled. Schematic contains many components. How to chek them all... 

Add new parameter only support for one project, if you want to add the same key at other project you need to add it again since 6.4.20.6, we remove the Add into Bom option, because of when export the BOM, you can chose the parameter key as you want, you don't need to set Add into BOM again.

Why they start duplicating? 

HI [Klyuzhev](https://easyeda.com/Klyuzhev), were you able to fix your issue ? I have been updating my project BOM but it wont display when I click on it, similar to yours

@wilder.gomez No, I can not find proper way to fix that stupid bug. Especially on big schematic with a lot of components.

@Klyuzhev  I was able to fix it manually, I also received the PCB and it worked but yes it was a hustle

Hi The new custom properties only for the current project files Can you repeat this issue at v6.4.29? I cannot repeat it, please send your schematic as EasyEDA format and send to [[email protected]](mailto:[email protected]) we will help to check thanks
