[7.10HF3]UI - Different equipment lists shown if xenon ship is part of selection

[BitByte]

Version 7.10 hotfix 3 English from GOG with SV, CoH & ToA DLCs no mods
OS: Windows 10

Description:
I was going to upgrade just claimed Mamba and Xenon B in Free Families Equipment Dock. I selected both ships, opened upgrade view and made changes to Xenon B. Then I opened S-size ship list and Mamba appeared but I couldn't change engine, thursters, shields nor weapons as tabs were either totally empty or only equipment installed was visible.
I tried same with Zyard Wharf but same result. Then I tested in Ministry of Finance EQ and still it was showing same. If I left Xenon B away from selection then Mamba's equipment list looked normal and I was able to choose what I wanted.

If single Xenon M-size ship (PE or B) and single common faction S-size ship (e.g. Mamba) are selected and click "upgrade" on NPC EQ/Wharf Xenon ship selection is limited like it should but when you select from list Mmaba there's no equipment to select. Only installed engine, shield(s) and weapon(s) can be seen. Thursters list is empty.

If single or multiple Xenon M-size ships (B needs be 1 of them and PE) + atleast 1 common faction M-size ship (e.g. Cerberus Vanguard) and single common faction S-size ship (e.g. Mambe) are selected and select "upgrade" on NPC EQ/Wharf Xenon ship selection is limited like it should be and if you at this point change to S-size ship again list is near empty.
But if you choose Cerberus Vanguard until change to S-size ship then equipment list is ok. Now from S-size ship change back to M-size and as Xenon B loadout appears you can change thursters to that ship which is not possible when click ship from the top screen list.
If last edited ship is Xenon ship until you change ship size and if first ship is common faction ship then equipment list is limited.

With Xenon SE this issue does not exist as it have little bit wider selection available (you can change thursters).

Reputation with Zyarth, Paranid, Teladi, Argon and Antigone is over +20, with Ministry and Free Families over +10 (below +20) so tests can be done with different factions.

Test scenario:
In Zyarth's Dominion I there's Xenon B (B XEN) and Mamba (Mamba ZYA) near player ship (Falcon). Select B XEN and Mamba ZYA, right click any faction EQ or Wharf and choose "Upgrade". Change from top selections ship size to S and Mamba appears. Check equipment list.

If need you can find Cerberus Vanguard (Cerberus VA ARG) parked in Ministry EQ located in Bright Promise. There's also Xenon PE (PE XEN) and Xenon SE (SE XEN). Cobra ZYA and Xenon ships can also be found to use in Zyarth's Wharf (Zyarth's Dominion IV).
