Custom plugins not visible on iPad in one vault

I’m having a strange problem with one of my vaults. I have some custom plugins that I have made that is working fine in several vaults but in this particular one they don’t show up in the list. I’ve reloaded and manually re copied them several times. All the files are there. But none of them is showing up in the plugins list in obsidian. What can I do? Plugins installed from the community plugins browser works as they should. The problem is only with this one vault. Nothing special compared to my other vaults.
