Thanks for reporting this. This issue seems to affect all LMX* land patterns in Ultiboard, and we're working on resolving this for the next major release. In the meantime, I have added a list of land pattern substitutions that should be used as replacements for these parts. (Note: If you are using any of the LMX* parts in Multisim, you will not be affected by this issue since the components in Multisim are linked to the correct land patterns in Ultiboard).
- LMX17AH -> TO39
- LMX17AK -> TO3
- LMX17AT_H -> TO220
- LMX17AT_V -> TO220
- LMX23AK -> TO3
- LMX33K -> TO3
- LMX33T_H -> TO220
- LMX33T_V -> TO220
- LMX37H -> TO39
- LMX40LAH -> TO39
- LMX96K -> TO3
