[BUG] Assets IOC column filtering does not work

[thomas-x64]

Describe the bug
Unfortunately its not possible to filter for IOC in the Assets overview. Neither the column nor the general search work.

To Reproduce
Steps to reproduce the behavior:

1. Go to Assets (in working case)
2. Filter for something in the IOC column
3. The first character entered results into an empty list

Expected behavior
The table should be filtered as expected

Screenshots

Additional context
Seems to be a general bug regarding IOC and mapping, perhaps some serialization thing. Export doesnt work proper as well, but I'll add a seperate Issue for that.

Thanks!
